Question

1/1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7+...
= (1/1 + 1/2 + 1/4 +1/8+ ...) + (1/3 + 1/6 + 1/12 + 1/24 + 1/48 +... ) + (1/5 + 1/10 + 1/20 + 1/40 + 1/80 +...)+...
={(1/1 /(1-1/2) } + {(1/3/(1-1/2)} +{1/5/(1-1/2)}+...
= 2(1/1) + 2(1/3) + 2(1/5)+...
=2(1/1 + 1/3 + 1/5 + 1/7 + 1/9+...)
So,
1/1+1/2+1/3+1/4+...=2(1/1+1/3+1/5+1/7+...)
1/2+1/4+1/6+1/8+...=1/1+1/3+1/5+1/7+...
1/2-1/3+1/4-1/5+1/6-1/7+1/8+...=1

Answer 1
