Question

If -2/7,x,7/2 are in GP then find x​

Answer 1

Answer:

One formula:

2 x Middle number = First number + Third number

Learn this formula

According to the question

middle number = x

first number = -2/7

third number = 7/2

now put these values in formula,we get

2 x = -2/7 + 7/2

2 x = -4 + 49/14 (since taking LCM as 14)

2 x = 45/14

x = 45/14 x 1/2 = 45/28
