WitrynaSince this holds for all n, we can plug in n=-1 and n=1 to get two equations: 1/-3=A/-1 +B/3. 1/5=A/1+B/5. Clean up the fractions to get -1=-3A+B and 1=5A+B. Subtract the second equation from the first to get -2=-8A, or A=1/4. So B=-1/4. So now, we're seeking the sum from n=1 to ∞ of (1/ (4n)-1/4 (n+4)).
