Question

Is the term 344 belongs to the AP-5,2,9..

Answer 1

344 does not belong to AP

Step-by-step explanation:

AP : -5,2,9..

First term = a = -5

Common difference = d = 2-(-5)=9-2=7

Formula of nth term in AP = $a_n=a+(n-1)d$

We are supposed to find 344 belongs to the AP-5,2,9..

Substitute the values in the formula :

344=-5+(n-1)(7)

349=(n-1)7

$n=\frac{356}{7}$

Since n is not a whole number

So, 344 does not belong to AP
