Advanced Math practice question

Answer: 5

Each step back halves the value: h(2) = 20, h(1) = 10, h(0) = 5.

Common wrong answers

If you answered 10

10 is h(1).

If you answered 34

34 subtracts 2 three times, treating the rule as additive.

If you answered 320

320 doubles three times instead of halving.
