Final answer:
The first three terms of the sequence 25 - 3n are 22, 19, and 16, found by substituting the values 1, 2, and 3 for n.
Step-by-step explanation:
To find the first three terms of the sequence 25 - 3n, we simply need to substitute the first three natural numbers (n = 1, 2, and 3) into the expression given.
- For n = 1: 25 - 3(1) = 25 - 3 = 22
- For n = 2: 25 - 3(2) = 25 - 6 = 19
- For n = 3: 25 - 3(3) = 25 - 9 = 16
Therefore, the first three terms of the sequence are 22, 19, and 16.
