Step-by-step explanation:
Let five geometric means are inserted between 32/3 and 243/2
then find sum of all the geometric
means.
GP becomes
a ar ar^2 ar^5 ar^6
a = 32/3 ar^6 = 243/2
r is common ration
ar to ar^5 are 5 geometric mean inserted
ar^6 / a = (243/2)/(32/3)
r^6 = 729/64
r^6 = 3^6/2^6
r = 3/2
ar = (32/3)*(3/2) = 16
GP of geometric mean
16 , 16×3/2 , 16 ×(3/2)^2 , 16×(3/2)^3 , 16×(3/2)^4
a = 16 r = 3/2 n = 5
Sum =.a (r^n -1)/(r-1)
= 16 ((3/2)^5 - )/(3/2 -1)
= 16 (243/32 - 1) /(1/2)
= 32 ( 211/32)
= 211
