Problem A job posted at jobstreet.com offered a starting salary of \$40,000 per year and guaranteeing a raise of \$1600 per year for the rest of 5 years. Write the general term for the arithmetic sequence that models potential annual salaries.

Answer Key

Solution

$a_n = 40,000 + (n - 1)(1600)$

$a_n = 40,000 + 1600n - 1600$

$a_n = 38,400 + 1600n$ ← Answer: [ A ]
