What are the first three terms in the sequence for -2n+5?

Answer 1

To find the first three terms of the sequence defined by the formula \(-2n + 5\), we will substitute \(n\) with the values 1, 2, and 3.

1. For \(n = 1\): \[ -2(1) + 5 = -2 + 5 = 3 \]

2. For \(n = 2\): \[ -2(2) + 5 = -4 + 5 = 1 \]

3. For \(n = 3\): \[ -2(3) + 5 = -6 + 5 = -1 \]

Therefore, the first three terms of the sequence are 3, 1, and -1.
