"WebDoh. Thanks. You can see that 2 + 1 - 3 = 0, so the cancellation occurs over three terms instead of two, so as you can see here if you added them together, all the fractions with [latex]k+1[/latex] on the denominator cancel out. To be honest, though, this is far more complicated than what would come up in an exam. " - Series method of differences
