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

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

   hope it helps
