Answer 1

Answer:

The first four term of the AP are 7, 3, -1, -5

Step-by-step explanation:

a = 7

$a + d = 7 - 4 = 3\\a + 2d = 7 - 8 = -1\\a + 3d = 7 - 12 = -5$

Answer 2

Answer:

a = 7

d = -4

a2 = 7+(-4)

a2 = 3

a3 = 7+2(-4)

a3 = -1

a4 = 7+3(-4)

a4 = -5

therefore first four terms are 7, 3, -1, -5.......
