Question 1108734
<br>
You are on the right track....<br>
But the "2x2=4", "3x3=9", etc. are the DENOMINATORS of the terms of the sequence.<br>
So the 1st term is {{{1/(1*1) = 1/1 = 1}}}
The 2nd term is {{{1/(2*2) = 1/2^2 = 1/4}}}
The 3rd term is {{{1/(3*3) = 1/3^2 = 1/9}}}
The 4th term is {{{1/(4*4) = 1/4^2 = 1/16}}}
...<br>
So what is the expression for the n-th term?
