Question

Write an explicit formula ((an = a1 + (n - 1)d) for the given arithmetic sequence. Use your formula to find the 50th term of the sequence

Answer 1

To write the explicit formula for an arithmetic sequence, we use the formula:

\[
a_n = a_1 + (n - 1)d
\]

where:
- \( a_n \) is the \( n \)-th term,
- \( a_1 \) is the first term,
- \( d \) is the common difference, and
- \( n \) is the term number.

To proceed, we need the values of \( a_1 \) and \( d \). Please provide them, and I can help you write the explicit formula and find the 50th term.
