Question

Find x
sothat 9, x, 4 are consecutive terms of a G.P. solve cheyyu

​

Answer 1

Answer:if the terms are in gp then they are in the form:

a, a.r, a.r²,so on......

here terms are 9,x,4

Therefore,a=9; a.r=x; a.r²=4

a.r²/a=4/9

r²=4/9

√r²=√2*2/3*3

r=2/3

a.r²/r=a.r

4/(2/3)=x

4*3/2=x

x=2*3

x=6
