Answer 2

Heya Mate!!

Here is your answer!!

Hence,

           An = 83

           a = 8

           d = 13 - 8

              = 5

==> An = a + (n - 1) d

==> 83 = 8 + (n - 1) 5

==> 83 - 8 = (n - 1) 5

==> 75 = (n - 1) 5

==> 75/5 = (n - 1)

==> 25 = n - 1

==> 25 + 1 = n

==> n = 26

So, the 26th term of A.P. is 83.
