prove by induction algebra help!

a sequece of integers x1,x2...xk..is defined recursively as follows:

x1=1 and xk+1 =xk/xk+2 for kis greater then or equal to 1

calculate x2,x3 and x4...i got

k=1:x1+1 =x1/x1+2=1/1+2=3=x^2

k=2:x2+1 =x2/x2+2=3/3+2=3=x^3

k=3:x3+1 =x3/x3+2=3/3+3=4=x^

is this right and another question using the info in the fisrt part how do i find and prove by induction a formula for the nth term xn in terms of n for all n is greater than or equal to 1,calcilate x10.

This is also not clear, if then:

Do you mean something like this? ...
