Question

In an AP, if a = 3.5, d = 0, n = 101, then a_n will be ______.

विकल्प

• 0

• 3.5

• 103.5

• 104.5

Answer 1

In an AP, if a = 3.5, d = 0, n = 101, then a_n will be 3.5.

Explanation:

We know that n^th term of an AP is

a_n = a + (n – 1)d

Where,

a = first term

a_n is n^th term

d is the common difference

a_n = 3.5 + (101 – 1)0

= 3.5  ...(Since, d = 0, it’s a constant A.P)
