Question

the nth term of ap is 6n+2 find common differences​

Answer 1

Answer:

as the first term is 6+2 = 8

second term is 6*2+2= 14

so d= 14-8

d= 6

Answer 2

Step-by-step explanation:

This is a question taken from class X RD Sharma (pg 9.11) and was also asked by CBSE in 2008.

The answer to this question is:

Nth term of ap is 6n+2

Therefore an =6n+2

Let n =1,2,3,4

If n equals 1 then a1=6+2=8

If n equals 2 then a2=12+2=14

If n equals 3 then a3 =18+2=20

Their common difference d=a3-a2=20–14=6

Therefore common difference is 6
