Answer :
x = 2
Explanation:
Let a= x ,b = x+2 , c = x+6
Now ,
b² = ac
[ Since , a,b and c are in
G.P]
=> (x+2)² = x(x+6)
=> x²+4x+4 = x²+6x
=> 4 = x²+6x-x²-4x
=> 4 = 2x
=> (4/2) = x
=> 2 = x
Therefore,
x = 2

Answer:
X = 2.
Step-by-step explanation:
G.P. a, a2, a3, a4, ....
r = a2/a1 = a3/a2 = a4/a3 = K
tn = ar^n - 1
a, ar, ar^2
G.P. if a, b, c are G.P. then
∴ X = 2.
