Question

Is 0 a term Ap 31, 28, 25,.....? Justify your answer

Answer 1

In this AP

a=31

d=-3

Let's see wheater 0 is term of AP or not and for that

we have to use the nth term formula

a+(n-1)*d=nth term

31+(n-1)*(-3)=0

31+-3n+3=0

34=3n

n=34/3

here the value of n is not a natural number

therefore,

it is not the term of an AP
