Question

Find four number in gp whose sum is 85 and product is 4096

Answer 1

Answer:

1 , 4 , 16 & 64

Step-by-step explanation:

let say 4 numbers are

a  ar  ar^2 ar^3

sum = a (1+r + r^2 + r^3) = 85

Product = a*ar*ar^2*ar^3 = a^4r^6 = 4096

a^2r^3 = 64

if a =1 then r = 4 then numbers are 1 , 4 , 16 & 64
