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 = -1.25, d = -0.25

Let the first four terms of arithmetic progression be a1, a2, a3, a4
Given, First term a = -1.25 and common difference d = -0.25.
⇒ a1 = a = -1.25
⇒ a2 = a1 + d = -1.25 + (-0.25) = -1.5
⇒ a3 = a2 + d = -1.5 + (-0.25) = -1.75
⇒ a4 = a3 + d = -1.75 + (-0.25) = -2.00


Hence, First four terms are -1.25, -1.5, -1.75, -2.00.
