Find whether -150 is a term of the AP 17,12,7....?

Answer 1

Hey nice question
Here is your's question answer

Here, 17,12,7....
Is an AP

a =17
d = - 5

By the formula
tn =a +(n-1) d
-150 =17 +(n - 1) (-5)
-150 =17 - 5n +5
-150 =22 - 5n

-150 - 22 =-5n

-172 = - 5n
- 172 /-5 = n
172 /5 = n

According to the given AP the terms are integers
Hence - 150 is not in the AP
