In an arithmetic sequence, the first term is 5 and the common difference is 3. What is the 8th term in the sequence?

Step 1 ：The nth term of an arithmetic sequence can be found using the formula \(a + (n-1)d\), where a is the first term, d is the common difference, and n is the term number.

Step 2 ：Substitute 5 for a, 3 for d, and 8 for n in the formula: \(5 + (8-1)3\)

Step 3 ：Simplify the expression: \(5 + 21 = 26\)
