Show that  C0/2 + C1/3 + C2/4 + ......... + Cn/n+2 = (1+n.2(n+1))/(n+1)(n+2)

Please tell me the answer to this question. Need urgently. Help from meritnation experts would be commendable . Please help !

Hi Manish!
Here is the proof of your question.
 
It is known that: C0 + C1x + C2x2 + C3x3 + …. Cnxn = (1+ x)n
⇒ C0x + C1x2 + C2x3 + C3x3 + …. Cnxn + 1 = x(1+ x)n
 
 Let z = 1 + x
dz = dx
When x → 0, z → 1
When x → 1, z → 2
 
Thus from equation (1)
 
Hope! You got the proof
Cheers!
