n=14 this is your answer hope this helps you

Answer 2

Concept

An arithmetic progression, popularly known as an AP is a set of numbers in sequence such that the difference between any two consecutive terms is a constant value.

The formula for finding the nth term of an AP is

an = a+(n-1)d

where an is the nth term

a is the 1st term

and d is the common difference

Given

An AP 6 13 20 27 ....

Find

We have to find which term of the AP is 97

Solution

Here we have,

a = 6

d = 13- 6 = 7

Thus, 97 will be which term can be calculated as-

97 = a+(n-1)d

97 = 6+(n-1)7

97- 6 = (n-1)7

13 = n-1

14= n

Thus, 97 is the 14th term of the given AP.
