WebA geometric series is a sequence of numbers in which the ratio between any two consecutive terms is always the same, and often written in the form: a, ar, ar^2, ar^3, ..., … WebApr 23, 2024 · Now, determine the interval: −2 < x + 2 < 2. −4 < x < 0. Test these endpoints: x = 0: ∞ ∑ n=2 2n 2n lnn = ∞ ∑ n=2 1 lnn. We'll use the Direct Comparison Test: 1 n ≤ 1 ln(n) on [2,∞), we know this because the logarithm grows slower, and the smaller denominator ensures a larger sequence, so, since the smaller series ∞ ∑ n=2 1 ...
