Roughly speaking there are two ways for a series to converge: As in the case of ∑ 1 / n2, the individual terms get small very quickly, so that the sum of all of them stays finite, or, as in the case of ∑ ( − 1)n − 1 / n, the terms do not get small fast enough ( ∑ 1 / n diverges ... Then applying the ratio test will give: Formula 4: Interval of Convergence pt. 2. After taking the limit, set r < 1 and then manipulate the inequality so that it takes the form of |x-a| < R, where R is the radius of convergence. The interval of convergence is the value of all x's, for which the power series converges. Interpreting test results. Normal urine elimination is less than 150 mg total protein per day and less than 30 mg albumin daily. The urine total protein to creatinine ratio or UPCR (mg/mg) is normally less than 0.2 for adults.
