Question

use the initial term and the recursive formula to find an explicit formula for the sequence $a_n$. write your answer in simplest form. $a_1 = 50$ $a_n = a_{n - 1}$ $a_n = \square$

Explanation:

Step1: Analyze recursive formula

The recursive formula is $a_n = a_{n-1}$, meaning each term equals the prior term.

Step2: Use initial term

Given $a_1 = 50$, every term matches the first term.

Answer:

$a_n = 50$
