A. P. 1


The 1st term of arithmetic progression is 37 and the common difference is 40. Find the nth term

solution

A1=37, d= 40, n=?

An =A1 + (n-1) d

An=37 + (n-1)40

An=37 + 40n -40

An=40n + 37-40

An=40n – 3

Hence the nth term is An=40n – 7  

TRY THIS………………….. 

The 1st term of arithmetic progression is 48 and the common difference is 98. Find the nth term.
