Question

check whether-153 is term of the AP:11,8,5,2......​

Answer 1

Answer:

ANSWER

Here,a=11,d=8−11=−3

Let −150 be the nth term of the given A.P.

We know that,a

n

=a+(n−1)d

−150=11+(n−1)×−3

−150=11−3n+3

(−150)+(−14)=−3n

−3n=−164

3n=164

n=

3

164

So,it is clear that n is not an integer.

Therefore,−150 is not a term of the given A.P.

Answer 2

Answer:

here a = 11

d = 8-11 = -3

an = a+ (n-1) d

-153 = 11 + (n-1) *-3

[(-153)+(-11)]/(-3) = (n-1 )

(-164)/(-3) = (n-1)

-164 is not divisible by 3 so -153 is not the term in the followin ap
