Question

If the nth term of an A.P. is 6n – 4, then its common difference is
6
6
8
-8​

Answer 1

Given:

nth term of an A.P [a_(n) ]= 6n-4

To find:

The common difference of the arithmetic progression

Calculation:

First term of the arithmetic progression is given by

     => a_(1) = 6(1) - 4

                  = 2

Second term of the arithmetic progression is given by

     => a_(2) = 6(2) - 4

                  = 8

Common difference(d)  = a_(2) - a_(1)

                                       =  8 - 2

                                       = 6

The common difference of the arithmetic progression(d) is 6
