Question

16) Cheak if the 0 is a term of the AP
31, 28,25​

Answer 1

Answer:

Let 0 be the nth term of given AP i.e., an = 0.

Given that, first term a = 31, common difference, d = 28 – 31 = – 3

The nth terms of an AP, is

an = a + (n-1)d

⇒ 0 = 31 + (n-1)(-3)

⇒ 3(n-1) = 31

⇒ n-1 = 31/3 + 1 = 34/3 = ⅓

Since, n should be positive integer. So, 0 is not a term of the given AP.

Answer 2

Answer:

No, 0 is not a term of the A.P.

Step-by-step explanation:

First term (Represented by a) = 31

Common Difference (Represented by d) = 31-28 = 3

Hence, the A.P. will be 31, 28, 25, 22, 19, 16, 13, 10, 7, 4, 1, -2 and 0 is between terms of the A.P. 1 and -2 hence it is not a term.
