Question

find the whether -150 is a term of the ap. 17 ,12, 7 ,2....? ​

Answer 1

This is a decreasing type a. p.

where a=17 and d=12-17=(-5)

now, to check whether -150 is a term of this ap

a(n)=a+(n-1)d

-150=17+(n-1)(-5)

-150-17= -5n+5

-167-5= -5n

-172= -5n

-172/-5 =n

n is not an integer hence -150 is not a term of this ap
