Final answer:

To find the first 3 terms of the sequence defined by f(n) = 25n - 5, substitute n with 1, 2, and 3, respectively, resulting in the terms 20, 45, and 70.

Step-by-step explanation:

The first 3 terms of the sequence defined by the rule f(n) = 25n - 5 can be found by plugging in the first three positive integers for n.

  1. For n=1: f(1) = 25(1) - 5 = 20
  2. For n=2: f(2) = 25(2) - 5 = 45
  3. For n=3: f(3) = 25(3) - 5 = 70

Therefore, the first three terms are 20, 45, and 70.
