Question

Find first four terms of an AP for which a =4 and d=-3.​

Answer 1

Answer:

a = 4

d= -3

a2 - a1 = d

a2= -3 +4

a2 = 1

similarly, a3 = -2

a4 = -5

Answer 2

Answer:

Four terms of an AP are 4 , 1 , -2 , -5

Step-by-step explanation:

Given: a = 4 , d = -3

a1 = a = 4

a2 = a + d = 4 +(-3) = 4-3 = 1

a3 = a +2d = 4+2(-3) = 4-6 = -2

a4 = a +3d = 4+3(-3) = 4-9 = -5
