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 = 20,

Let the first four terms of arithmetic progression be a1, a2, a3, a4
Given, First term a = 20 and common difference d = .
⇒ a1 = a = 20
⇒ a2 = a1 + d =
⇒ a3 = a2 + d =
⇒ a4 = a3 + d =


Hence, First four terms are .
