A. P. = 11, 8, 5, 2 ......

For, - 150

An = a+ ( n - 1 ) d

-150 = 11 + ( n - 1 ) ( - 3 )

- 150 / - 3 = 11 + n - 1

50 = 10 + n

n = 50 - 10

n = 40.

Hence, An = 11 + ( 40 - 1 ) ( - 3 )

An = 11 - 39*3

An = 11 - 117

An = -106

Last term is - 106 and total number of terms are 40.

So, -150 is not the term of this A. P.
