Question

If 2x‚x+10‚3x+2are AP.find the value of x

Answer 1

If three terms are in AP, then 2 times the middle term is equal to the sun of 1st and 3rd term.
so,
=> 2(x+10)= 2x + 3x+2
=> 2x +20 = 5x +2
=> 5x - 2x = 20-2
=> 3x = 18
=> x = 6
terms are 12, 16, 20

Answer 2

→(x+10)-(2x)=(3x+2)-(x+10)
→x+10-2x=3x+2-x-10
→10-x=2x-8
→3x=18
→x=18/3
→x=6
