In an A.P. the two consecutive terms are (2n+3) and (2n+5). Find the common difference of the A.P.
2
2n+1
2n+2
2n+3
Common difference is found out by taking the difference of the consecutive terms.
So, common difference = (2n + 5) - (2n + 3) = 2
If nth term of an A.P. is 2n+1, then find its common difference.
