Answer:

if they r in AP

then

2(6x-2) =2x-7+8x+9

12x-4=10x+2

2x=6

x=3

terms are

33,16 and -1

Answer 2

Answer:

3

Step-by-step explanation:

In AP diffference of consecutive terms must be equal,

Therefore, 8x + 9 - ( 6x -2 ) = ( 6x - 2 ) - (2x - 7 )

8x + 9 - 6x + 2 = 6x - 2 - 2x + 7

2x + 11 = 4x +5

2x =6

x = 3

Therefore the terms are,

8(3) + 9 = 33

6(3) - 2 = 16

2(3) - 7 = -1
