Q2 of 67 Page 65

If for any arithmetic progression first term a and the common difference d are graph as follows, then write first four terms of that progression-

a = 4, d = -3

Let the first four terms of arithmetic progression be a1, a2, a3, a4
Given, First term a = 4 and common difference d = -3.
⇒ a1 = a = 4
⇒ a2 = a1 + d = 4 + (-3) = 1
⇒ a3 = a2 + d = 1 + (-3) = -2
⇒ a4 = a3 + d = (-2) + (-3) = -5


Hence, First four terms are 4, 1, -2, -5.
