Get the NCERT Books for Session 2022-23 and solve the question given on Page No:99 Chapter 5 EXERCISE 5.1 Questions No:2 Part (iv).
Write first four terms of the AP, when the first term a and the common difference d are given as follows: a = – 1, d = 1/2
Share
a = – 1, d = 1/2
First term a₁ = a = – 1
Second term a₂ = a₁ + d = – 1 + 1/2 = – 1/2
Third term a₃ = a₂ + d = – 1/2 + 1/2 = 0
Fourth term a₄ = a₃ + d = 0 + 1/2 = 1/2.
