What are the first three terms in the sequence for 7n-3?

Answer 1

To find the first three terms of the sequence defined by the formula \( 7n - 3 \), we will substitute \( n = 1, 2, \) and \( 3 \) into the formula.

1. For \( n = 1 \): \[ 7(1) - 3 = 7 - 3 = 4 \]

2. For \( n = 2 \): \[ 7(2) - 3 = 14 - 3 = 11 \]

3. For \( n = 3 \): \[ 7(3) - 3 = 21 - 3 = 18 \]

Thus, the first three terms of the sequence are \( 4, 11, \) and \( 18 \).
