The very first constraint sets the degree of expected return. Sum of series. A series is absolutely convergent if the series converges and it also converges when all terms in the series are replaced by their absolute values.. The average ratio of a geometric series could possibly be negative, causing an alternating sequence. Also, be careful when you write fractions: 1/x^2 ln(x) is `1/x^2 ln(x)`, and 1/(x^2 ln(x)) is `1/(x^2 ln(x))`. Determine if the following series converges or diverges. – series diverged. If we wasn't able to find series sum, than one should use different methods for testing series convergence.
