Question

Find the value of X for which the numbers (5x+2),(4x-2)and (X+2) are in ap

Answer 1

Answer:

x=4

Step-by-step explanation:

For three numbers to be in ap, the second number should be the arithmetic mean of the first and third.

4x-2=(5x+2+x+2)/2

4x-2=3x+2

x=4

Answer 2

Step-by-step explanation:

5x+2,4x-2,x+2

d=4x-2-(5x+2)=x+2-(4x-2)

4x-2-5x-2=x+2-4x+2

-x-4= -3x+4

-x+3x=4+4

2x=8

x=4
