Find the first four terms of the sequence defined below, where n represents the position of a term in the sequence. Start with n = 1.

an = n − 54

1 answer

To find the first four terms of the sequence defined by the formula \( a_n = n - 54 \), we will substitute values of \( n \) from 1 to 4.

  1. For \( n = 1 \): \[ a_1 = 1 - 54 = -53 \]

  2. For \( n = 2 \): \[ a_2 = 2 - 54 = -52 \]

  3. For \( n = 3 \): \[ a_3 = 3 - 54 = -51 \]

  4. For \( n = 4 \): \[ a_4 = 4 - 54 = -50 \]

So, the first four terms of the sequence are: \[ -53, -52, -51, -50 \]
