Solution 1

a) Para encontrar el término a8 de la secuencia {an} donde an = 2n - 1, sustituimos n por 8:

a8 = 2(8) - 1 a8 = 16 - 1 a8 = 15

b) Si an = 7, entonces todos los términos de la secuencia son 7, incluyendo a8:

a8 = 7

c) Para encontrar el término a8 de la secuencia {an} donde an = 1 + (−1)n, sustitu Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
