Solution

The correct option is B

4


Given, nth term of an AP (Tn)=2+4n
T1=2+4(1)=6
T2=2+4(2)=10
d=T2T1 =106 =4

Alternate method:
The general term is represented by Tn=a+(n1)d.
The coefficient of 'n' in the expression of the general term of an AP is the common difference of the AP.
Tn=(ad)+nd.
Comparing with 2+4n
We get the common difference, d = 4.
