Question

what is the common difference of an a.p. whose n term is 3 + 5n

Answer 1

ist term = 3 + 5(1) = 8

2nd term = 3 + 5(2) = 13

common difference = 13 - 8 = 5

Answer 2

hello friend....

here is the solution

we have given that
n th term of AP is = 3+5n

so ,here
a1 = 3+ 5 ×1 = 8
&
a2= 3+ 5× 2= 3+10= 13

now
we know that
common deference (d) = a2 - a1

= 13-8 = 5 answer

## Hope it helps##
