What is the value of the following expression?
(1/ (2^2 – 1)) + (1/ (4^2 – 1)) + (1/ (6^2 – 1)) + .... + (1/ (16^2 – 1))
Choose the correct choice from the following choices:	A) a. 9/19	B) b. 10/19	C) c. 10/21	D) d. 11/21	E) e. 8/17
it can be written into   1/3+1/15+ 1/35.....1/256   i.e   1/3+1/2*(1/3-1/5)+1/2*(1/5-1/7).... til last term - 1/2*(1/17)   all terms from 1/5 .. to second last term get cancelled   left with   1/3+1/6-1/34=1/2-1/34=16/34=8/17   e. 8/17
<result>E</result>
