Insert two number between 3 and 81 so that the resulting sequence is G.P.

Answer

N/a

Explanation

Let required numbers be a and b . Then, the sequence 3,a,b 81 will be in G.P.
`a_(4)=81`
`implies 3r^(3)=81implies r^(3)=27`
`implies r=3`
`:. A=3xxr=3xx3=9`
`b=a_(1)xxr^(2)=3xx9=27`
Therefore, number and 9 and 27
