Answer 2

Hello frnd!

Hope this may help you.! :)

• The sum of this series is -1/12 . This can be proved by Riemann zeta function.

• But ramanujan have proved it by a different method as follows…

• Let,

• X=1+2+3+4+5+6+… ____(1)

• 4X= 4 + 8 + 12 +...____(2)

• =>-3X=1–2+3–4+5–6+… (subtracting 2 from 1)

• =>-3X=1/(1+1)^2 _____by binomial theoram

• =>-3X=1/4

• =>X=-1/12

Proved.
