Answer 2

Given :

AP: 117,104,91,78  , ......

To Find :

Find the 8th term

Solution:

AP: 117,104,91,78  , ......

First term = a = 117

Common difference = d = 104-117=91-104= -13

Formula of nth term = A_n=a+(n-1)d

We are supposed to find the 8th term

Substitute n = 8

So,$A_{8}=117+(8-1)(-13)\\A_8=26$

Hence The 8th term is 26
