WebTo find r, we should look at the ratio between successive terms: r= \frac {a_ {1}} {a_ {2}} =\frac {6} {3} = 2. Then using the formula above we get a_ {n} = r^ {n-1} a_ {1} = 2^ {n-1} \cdot 3 . To find a_ {7} we set n=7 and get a_ {7} = 2^ {7-1} \cdot 3 = 2^ {6} \cdot 3 = 64 \cdot 3 = 192 . Part 3: Recursive Sequences 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
