Find first four terms of AP when the first term is 4 and the common difference is -3.

The correct answer is 4, 1, -2, -5

a = 4, d = - 3

First term, a = 4

Second term, a + d = 4 + (- 3) = 1

Third term, a + 2d = 4 + 2(- 3) = 4 - 6 = - 2

Fourth term, a + 3d = 4 + 3(- 3) = 4 - 9 = - 5

The first four terms of the AP are 4, 1, - 2, - 5.
