Question

Which are the terms of AP 3, 10, 17 will be 84 more than its 13 term

Answer 1

Answer :

The AP is 3, 10, 17, ...

So, the first term is 3 and the common difference is 7.

So, the 13th term is

= 3 + (13 - 1)(7)

= 3 + (12 × 7)

= 3 + 84

= 87

Thus, the term which is 84 more than its 13th term is

= 87 + 84

= 171
