Q. Evaluate the expression for n=−1n = -1.\newline−12n−16=-12n - 16 = _____
  1. Substitute n=−1n = -1: Substitute n=−1n = -1 into the expression −12n−16-12n - 16.\newlineSubstitute −1-1 for nn in −12n−16-12n - 16 to get −12(−1)−16-12(-1) - 16.
  2. Evaluate expression: Evaluate –12(–1)−16–12(–1) − 16.\newlineMultiplying –12–12 by –1–1 gives 1212, so the expression becomes 12−1612 − 16.
  3. Subtract to get result: Subtract 1616 from 1212. 12−1612 - 16 equals −4-4.
