A sequence is defined by the explicit formula a_n = -3n + 8. Which term of the sequence equals -22?

1. An explicit formula gives any term directly from its position n, so set the formula equal to -22. 2. Solve -3n + 8 = -22: subtract 8 from both sides to get -3n = -30. 3. Divide by -3 to get n = 10, so the 10th term equals -22. 4. Checking n = 9 gives -19 and n = 11 gives -25, so neither neighboring position works. _Source: OpenStax Algebra and Trigonometry (CC BY 4.0), Ch 13 "Sequences, Probability and Counting Theory", section 13.1 SEQUENCES AND THEIR NOTATIONS_
