To find: Two geometric Mean

Given: The numbers are 9 and 243

Formula used : (i) r = \(\left(\frac{b}{a}\right)^{\frac{1}{n+1}}\) Where n is the number of geometric mean

Let G1 and G2 be the three geometric mean

G1 = ar = 9×3 = 27 

G2 = ar2= 9×32 = 9×9 = 81

Two geometric mean between 9 and 243 are 27 and 81.
