In addition of series of numbers which has a common difference are required to add all numbers which combined in a group and no isues are arise whether it is common difference or how many numbers are need to add in that case we consider as some short of rule to obtain the desire result.

So apart from that you only need some mathematical simple calculation to obtain the answer.

**Tricks :** we need to add the large number with small number, After that multiply this add result by count of numbers in the series of numbers, at last we have to do that we divide the result by 2.

Now let find the addition of following given numbers

Example #1 – Addition of Common difference in a Series of Numbers

39 + 49 + 59 + 69 + 79 = ?

The result of the addition is 39 + 49 + 59 + 69 + 79 = 295.

Shortcut Tricks

- Add the large number with small number,

i.e, 79 + 39 = 118 - Then Count the total numbers present in the series. In this case it is 5.
- Then multiply the Added result with the Number count,

i.e, 118 x 5 = 590 - At last divide the number by 2,

i.e, 590 / 2 =**295**.

Example #2 – Addition of Common difference in a Series of Numbers

36 + 44 + 52 + 60 = ?

The result of the addition is 36 + 44 + 52 + 60 = 192.

Shortcut Tricks

- Add the large number with small number,

i.e, 60 + 36 = 96 - Then Count the total numbers present in the series. In this case it is 4.
- Then multiply the Added result with the Number count,

i.e, 96 x 4 = 384 - At last divide the number by 2,

i.e, 384 / 2 =**192**.

Example #3 – Addition of Common difference in a Series of Numbers

77 + 82 + 87 + 92 + 97 = ?

The result of the addition is 77 + 82 + 87 + 92 + 97 = 435.

Shortcut Tricks

- Add the large number with small number,

i.e, 97 + 77 = 174 - Then Count the total numbers present in the series. In this case it is 5.
- Then multiply the Added result with the Number count,

i.e, 174 x 5 = 870 - At last divide the number by 2,

i.e, 870 / 2 =**435**.

Example #4 – Addition of Common difference in a Series of Numbers

i.e, 550 / 2 =**275**.

Example #6 – Addition of Common difference in a Series of Numbers

111 + 98 + 85 + 72 + 59 = ?

The result of the addition is 111 + 98 + 85 + 72 + 59 = 425.

Shortcut Tricks

- Add the large number with small number,

i.e, 111 + 59 = 170 - Then Count the total numbers present in the series. In this case it is 5.
- Then multiply the Added result with the Number count,

i.e, 110 x 5 = 850 - At last divide the number by 2,

i.e, 850 / 2 =**425**.

Example #7 – Addition of Common difference in a Series of Numbers

89 + 80 + 71 + 62 = ?

The result of the addition is 89 + 80 + 71 + 62 = 302.

Shortcut Tricks

- Add the large number with small number,

i.e, 89 + 62 = 151 - Then Count the total numbers present in the series. In this case it is 4.
- Then multiply the Added result with the Number count,

i.e, 151 x 4 = 604 - At last divide the number by 2,

i.e, 604 / 2 =**302**.

Example #8 – Addition of Common difference in a Series of Numbers

22 + 33 + 44 + 55 + 66 = ?

The result of the addition is 22 + 33 + 44 + 55 + 66 = 220.

Shortcut Tricks

- Add the large number with small number,

i.e, 66 + 22 = 88 - Then Count the total numbers present in the series. In this case it is 5.
- Then multiply the Added result with the Number count,

i.e, 88 x 5 = 440 - At last divide the number by 2,

i.e, 440 / 2 =**220**.

Example #9 – Addition of Common difference in a Series of Numbers

49 + 55 + 61 + 67 + 73 = ?

The result of the addition is 49 + 55 + 61 + 67 + 73 = 305.

Shortcut Tricks

- Add the large number with small number,

i.e, 73 + 49 = 122 - Then Count the total numbers present in the series. In this case it is 5.
- Then multiply the Added result with the Number count,

i.e, 122 x 5 = 610 - At last divide the number by 2,

i.e, 610 / 2 = 305

Thus 49 + 55 + 61 + 67 + 73 =**305**.

Example #10 – Addition of Common difference in a Series of Numbers

15 + 25 + 35 + 45 + 55 + 65 = ?

The result of the addition is 15 + 25 + 35 + 45 + 55 + 65 = 240.

Shortcut Tricks

- Add the large number with small number,

i.e, 65 + 15 = 80 - Then Count the total numbers present in the series. In this case it is 6.
- Then multiply the Added result with the Number count,

i.e, 80 x 6 = 480 - At last divide the number by 2,

i.e, 480 / 2 =**240**.

This method does not follow all the numbers

Ex: 86+12+3+25+90+8 = 234

If this is solved using the above method one will not find the correct answer.

This tricks only for common difference between numbers only…if between numbers differences is common then u apply this trick

its for series numbers not a single digits

is it possible for only five digits ya more also?

it is possible for more digits..multiply by no of digits in series instead of 5

ex 36,44,52,60,68,76(total no of digit is 6)

1.36+76=112

2.112*6=672

3.672/2=336

It is arithmatic progression.

S=(n/2)(a+l)

where S- Sum

n- number of values in series

a- first term

l- last term.

This is standard 7 formula, if you remember elementary mathematics.

This method is not working for series – 86+12+30+25+90+81 = 324

its not a common difference method series…. mam

This trick only works if there is a common difference in the series..

It is more easier if u can explain the logic too
