Question

Is 0 a term of the AP: 31, 28 ,25 ,........…? Justify your answer.

Answer 1

Answer:

no 0 is not a term of the AP

Step-by-step explanation:

A.T.Q

An= a + (n-1)d ....................... 1

here,

An= 0, a=31, n=?, d=-3

replacing values in 1

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

0= 31 - 3n+3

=>  34=3n

n=34/3

since n cannot be in fraction it is not a term of the given AP
