Answers
GPT-4o mini
To find the 57th term in the sequence defined by the expression \( 12 - 2n \), where \( n \) is the term number (with \( n = 1 \) for the first term):
1. Substitute \( n = 57 \) into the expression:
\[
a_{57} = 12 - 2 \times 57
\]
2. Calculate \( 2 \times 57 \):
\[
2 \times 57 = 114
\]
3. Now substitute this value back into the expression:
\[
a_{57} = 12 - 114
\]
4. Finally, perform the subtraction:
\[
a_{57} = 12 - 114 = -102
\]
Therefore, the 57th term of the sequence is \(-102\).
