One of my question has been reported by someone & i can't respond to it because it shows some problem is there.

I want to share my answer here, The question was to find 2S where S=1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+1-1+......... My answer was 2S=1. For more you can see grandi series.

What is meaning that the series will diverge?

The partial sum of the series does not converge to any fixed number.

You need to specify that you're using Cesaro sum, otherwise, the series diverge.
