First five term of the geometric sequnce is
{1 , 2.718 , 7.389 , 20.086 , 54.598 }

Explanation:

a_1=1 ,r=e = 2.7182818 ;n th term is a_n= a_1*r^(n-1)

:. a_2= 1*e^(2-1) = e ~~ 2.7182818 similarly ,

:. a_3= 1*e^(3-1) = e^2 ~~7.389(3dp)

:. a_4= 1*e^(3-1) = e^3 ~~ 20.086(3dp)

:. a_5= 1*e^(5-1) = e^4~~ 54.598 (3dp)

First five term of the geometric sequnce is

{1 , 2.718 , 7.389 , 20.086 , 54.598 } [Ans]
