1+11+111+1111+11111.... the geometric series can be summed to infinity. Find this sum
111....n times = 10^0 + 10^1 ... 10^(n-1) so we have 1 + 10 + 1 + 10^2 + 10 + 1 + 10^3 + 10^2 + 10 + 1..... => 1(n-1) + 10(n-2) + 10^2(n-3) ..... seems and AGP..you know AGP ?
dont think you meant infinity..did you? you want just sum upto n terms right>?
ohh well..is not an AGP,,r in AGP is <1 ..here is not the case..
