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 = 11, d = -4

Let the first four terms of arithmetic progression be a1, a2, a3, a4
Given, First term a = 11 and common difference d = -4.
⇒ a1 = a = 11
⇒ a2 = a1 + d = 11 + (-4) = 7
⇒ a3 = a2 + d = 7 + (-4) = 3
⇒ a4 = a3 + d = 3 + (-4) = -1


Hence, First four terms are 11, 7, 3, -1.
