HERE IS THE PROOF...................
y = 3/4 + ( 3.5 )/ ( 16 . 2! ) + ( 3.5.7 )/ ( 64 .3! )
+ ( 3.5.7.9 )/( 256 . 4! ).........
THEREFORE ,
y + 1 = 1 + ( the above expression )
= 1 + 3/4 + (3.5 )/ (4.8) + ( 3.5.7 )/ (4.8.12 ) + .............
( rearrangement of factorial has been done )
= ( 1 - 1/2 ) ^ ( -3/2 )..........binomial expansion
squaring.........
(y + 1 )^ 2 = 8
=> y^2 +2y - 7 = 0
=> y = sqrt (8) -1
hope u rate me for such a quality question................
AND DO WAIT FOR MY SEVENTH ONE ( A BIT SIMPLER )

HEY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 I got it yaar. But you have broken the thrill and suspense. Still I will put down my way of answering. 
y = 3/4 + 3.5/42.2! + 3.5.7/43.3! + ........................................................ y + 1 = 1 + 3/4 + 3.5/42.2! + 3.5.7/43.3! + .......................................... (1 + x)n = 1 + nx + n(n - 1)x2/2! + ................................................... nx = 3/4 nx(nx - x)/2 = 3.5/42.2! = 15/32 x = -1/2 ; n = -3/2 ie ; (1 + x)n = y + 1 = (1 - 1/2)-3/2 =  8  ie ; y = 8 - 1 SO, HOW'S THIS ???
