Question

use a graphing calculator to find the first 10 terms of the sequence (a_n = 2n + 3).
its 9th term is
its 10th term is

Explanation:

Step 1: Identify the sequence formula

$$a_n = 2n + 3$$

Step 2: Calculate the 9th term

$$a_9 = 2(9) + 3 = 18 + 3 = 21$$

Step 3: Calculate the 10th term

$$a_{10} = 2(10) + 3 = 20 + 3 = 23$$

Answer:

its 9th term is 21
its 10th term is 23
