Answer 2

Heya!!

------------------------------------------------------------------------------------------------------

◾Given that ,
===========

⭐AP = 11 , 8 , 5 , 2...........


✔First term a = 11

✔Common Difference d = -3

✔Nth term An = -150

↪We need to check if -150 is a term of the sequence !

Using the formula for An


An = a + ( n -1 ) d

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

-150 - 11 = ( n -1 ) 3

-161 / 3 = ( n -1 )

n = -161/3 +1


➡Here the value of N comes out to be in Fraction !! This isn't a possible value of N . Hence the Given number is NOT a term of AP!!
