Question

find the value of x so that -6,x,8are in arithmetic progressions​.​

Answer 1

Answer:

Given: (x+2),2x,(2x+3) are three consecutive terms of an AP.

So, difference between two consecutive terms will be same.

2x−(x+2)=(2x+3)−2x

2x−x−2=2x+3−2x

x−2=3

x=2+3=5

The value of x is 5.

Answer 2

1

AP means The common difference should be equal

x=(-6+8)÷2

x=1
