Find the 8^th term from the end of the AP 7, 9, 11, …., 201.

To find: 8^th term from the end

d = 9 - 7

d = 2

Also

201 = 7 + n × 2 – 2

n = 98

So 8^th term from end will be

7 + 90 × 2

⟹ 187

The 9^th term of an AP is 0. Prove that its 29^th term is double the 19^th term.

How many terms are there in the AP 13, 16, 19, …., 43?

How many 2 - digit numbers are divisible by 7?

If 7^th and 13^th terms of an AP be 34 and 64 respectively then find its 18^th term.
