Q. Evaluate the expression for n=1n = 1.\newline−13+18n=-13 + 18n = _____
  1. Substitute n=1n = 1: Substitute n=1n = 1 into the expression –13+18n–13 + 18n.\newline–13+18(1)–13 + 18(1)
  2. Evaluate expression: Evaluate the expression –13+18(1)–13 + 18(1).–13+18–13 + 18
  3. Add numbers together: Add −13-13 and 1818 together.\newline−13+18=5-13 + 18 = 5
