Question

Write the value of x for which 2x,x+10and 3x+2 are in ap

Answer 1

Answer:

x = 6

AP is 12, 16, 20

Step-by-step explanation:

2x, x + 10, 3x + 2 are in AP

(x + 10) - 2x = (3x + 2) - (x + 10)

x + 10 - 2x = 3x + 2 - x - 10

10 - x = 2x - 8

- x - 2x = - 8 - 10

- 3x = - 18

x = -18/-3

x = 6

therefore the AP is

2×6, 6+10, 3(6) + 2

12, 16, 20
