Question

What is the fifth term in the arithmetic sequence defined by the explicit formula an=6n−4?

Answer 1

The correct answer is 26.i took the test

Answer 2

In an explicit formula, n represents any term number and a(n) represents the value of the n-th term. Therefore, in order to find the fifth term, we simply solve for a(n) when n = 5. Plugging that value into the equation gives us a(5)=6(5)-4, or a(5) = 26. The fifth term is of the sequence is 26.
