Question

plzzz give me the answer​

Answer 1

Answer:

Here the AP is 11 ,8,5 ,2.....

so, we take -152 as a term of this AP ,if it satisfy(n is in whole no.) then it must be the term of this AP .

An = a + (n-1)d

-152 = 11 + (n-1)-3

-152 -11 = -3n +3

-163 -3 = -3n

-166 = -3n

hence, n = 55.3

the value is in point,so -152 not in this AP
