WebAnd, as promised, we can show you why that series equals 1 using Algebra: First, we will call the whole sum "S": S = 1/2 + 1/4 + 1/8 + 1/16 + ... Next, divide S by 2: S/2 = 1/4 + 1/8 + 1/16 + 1/32 + ... Now subtract S/2 from S All the terms from 1/4 onwards cancel out. And we get: S − S/2 = 1/2 Simplify: S/2 = 1/2 And so: S = 1 Harmonic Series
