If general term of an AP is given by 2 + 4n then find its common difference.
Given, nth term of an AP (Tn)=2+4n
⇒d=T2−T1 =10−6 =4
The general term is represented by Tn=a+(n−1)d.
The coefficient of 'n' in the expression of the general term of an AP is the common difference of the AP.
Comparing with 2+4n
We get the common difference, d = 4.
