Find the 20th term from the last term of AP 3,8,13.....253.

\bf\huge\underline{Answer}

We have, the last term (l) = 253

Here, d = 8 - 3 = 5

Since, then n term before the last term is given by l - (n - 1)d

Therefore, We have 20th term from the last term

=> l - (20 - 1) × 5

=> 253 - 19 × 5

=> 253 - 95

=> 158
