Question

Is –150 a term of the A.P 11,8,5,2, …?

Answer 1

Answer:

Step-by-step explanation:

we know that

the nth term in an AP is an=a+(n-1)d where n is a natural number

                  where an=-150

                              a=11

                              d=3 we have to find n

    -150=11+(n-1)3

     -161=(n-1)3

      n-1=53.66

        n=54.66(which is not a natural number)

so -150is not a term of AP 11,8,5,2
