Here it is proof for this:

Analytic continuation of the zeta function gives zeta(-1) = - 1/12.

If you want to know more pick up a book on complex analysis.

e.g. Alfhors

You should also know that this series diverges to +inf in the classical sense of convergence. i.e. 1 + 2 + ... = -1/12 should not be understood in the way 1+1/4+1/9+ ... = (pi^2)/6 is.
