Question

Verify whether130 is a term of the ap 3,7,11

Answer 1

Answer: 130 is not a term of the given A.P

Step-by-step explanation:

Here, First term a=3

Common difference d=11-7=4

Let 130 be the nth term of the given A.P.

We know that, an=a+(n−1)d

130=3+(n−1)×4

130=3+4n-4

130=4n-1

130+1=4n

131=4n

n=131/4

So, it is clear that n is not an integer.

Therefore,130 is not a term of the given A.P.
