The same rule turns each first number into the second. Find the missing one. How these questions work →
The same rule changes each first number into the second. Which number is missing?
The rule is: add 2, then multiply by 3 (9 → 33, 6 → 24, 4 → 18). So 3 → 15.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 3, then multiply by 3 (5 → 24, 3 → 18, 9 → 36). So 7 → 30.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 1, then multiply by 3 (5 → 18, 2 → 9, 3 → 12). So 6 → 21.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 3, then multiply by 2 (2 → 10, 4 → 14, 8 → 22). So 9 → 24.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 4, then multiply by 3 (7 → 33, 6 → 30, 2 → 18). So 9 → 39.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 2, then multiply by 2 (9 → 22, 4 → 12, 5 → 14). So 7 → 18.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 2, then multiply by 3 (5 → 21, 3 → 15, 2 → 12). So 9 → 33.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 4, then multiply by 3 (3 → 21, 6 → 30, 4 → 24). So 9 → 39.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 3, then multiply by 3 (2 → 15, 9 → 36, 5 → 24). So 4 → 21.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 1, then multiply by 2 (9 → 20, 4 → 10, 2 → 6). So 5 → 12.
