## Question:

The 50th term of an arithmetic sequence is 86, and the common difference is 2. Find the first three terms of the sequence.

## Arithmetic Sequences:

An arithmetic sequence is a sequence of numbers where each number is simply the last number plus or minus a value, known as the common difference. To find any term in these sequences, we use the formula: {eq}N = a_1 + (n - 1)d \\ {/eq} Where N is the value of the term, a is the initial value, n is the number of the term, and d is the common difference.
