First five terms are {1,1/(2sqrt2),1/(3sqrt3),1/8,1/(5sqrt5)}

Explanation:

As a_n=1/n^(3/2)

a_1=1/1^(3/2)=1

a_2=1/2^(3/2)=1/sqrt8=1/(2sqrt2)

a_3=1/3^(3/2)=1/sqrt27=1/(3sqrt3)

a_4=1/4^(3/2)=1/sqrt64=1/8

a_5=1/5^(3/2)=1/sqrt125=1/(5sqrt5)

Hence, first five terms are {1,1/(2sqrt2),1/(3sqrt3),1/8,1/(5sqrt5)}
