Question

2) The nth term of An Ap. is 6n+11
find the common difference​

Answer 1

6

Given:

The nth term of the AP = 6n + 1

To Find:

The common difference of the AP.

Calculating:

Finding the first term of the AP by,

Putting the value of n as 1:

= 6 x 1 + 11

= 6 + 11

= 17

Finding the second term of the AP by,

Putting the value of n as 2:

= 6 x 2 + 11

= 12 + 11

= 23

Now calculating the common difference of the AP by subtracting the second term from the first term:

= 23 - 17

= 6

Therefore, the common difference of the AP is 6.
