Question

the nth term of an AP is given by a^3=3+4n then it's common difference is
a)7
b)3
c)1
d)4​

Answer 1

Answer:

(d) 4

Step-by-step explanation:

It is given that the nth term of an AP is given by

an = 3 + 4n

So, a1 = 3 + 4(1) = 3 + 4 = 7

And, a2 = 3 + 4(2) = 3 + 8 = 11

Now, common difference = d

= a2 - a1

= 11 - 7 = 4
