Final answer:
The first three terms of the sequence defined by the nth term formula 25-3n are 22, 19, and 16, respectively, and the 10th term is -5.
Step-by-step explanation:
The student is asking about a specific arithmetic sequence where the nth term is given by the formula 25 - 3n. To find the first three terms of the sequence, we will substitute n = 1, n = 2, and n = 3 into the formula. For the tenth term, we will substitute n = 10.
- For n = 1: 25 - 3(1) = 22
- For n = 2: 25 - 3(2) = 19
- For n = 3: 25 - 3(3) = 16
- For n = 10: 25 - 3(10) = 25 - 30 = -5
Therefore, the first three terms of the sequence are 22, 19, and 16, and the 10th term is -5.
