How do antecedent states (like mood or momentary condition) influence consumer behavior? Can you state a personal example of how an antecedent state affected your buying/shopping behavior? Find the radius of convergence and interval of convergence of the series. Part 1 of 4 We have Part 2 of 4 n = 1 We will use the Ratio Test to determine the radius of convergence. X + 9 8n! lim 78 an + 1 an = lim n Simplifying, we get lim n + 10 8(n + 1)! + +9 8n! = lim x + 10 n 8(n + 1)! X 8 n! Xn +9
