Question

the first positive term of the ap -1,1-8,-5​

Answer 1

Answer:

Step-by-step explanation:

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.
