NCERT Class X Chapter 5: Arithmetic Progression Exercise 5.1 Question 2 (ii)

Question:

Write first four terms of the AP, when the first term a and the common difference d are given as follows: a = –2, d = 0

Given:

First term (a) = –2
Common difference (d) = 0

To Find:

First four terms of the Arithmetic Progression (AP)

Formula:

n^th term of an AP = a + (n-1)d

Solution:

First term (a₁) = a = -2

Second term (a₂) = a + d = -2 + 0 = -2

Third term (a₃) = a + 2d = -2 + 2(0) = -2

Fourth term (a₄) = a + 3d = -2 + 3(0) = -2

Result:

The first four terms of the AP are -2, -2, -2, -2
