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: multiply the number by itself, then add 6 (9 → 87, 3 → 15, 4 → 22). So 2 → 10.
The same rule changes each first number into the second. Which number is missing?
The rule is: multiply the number by itself, then add 1 (9 → 82, 8 → 65, 6 → 37). So 3 → 10.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 4, then multiply by 2 (8 → 24, 7 → 22, 5 → 18). So 4 → 16.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 5, then multiply by 3 (4 → 27, 8 → 39, 6 → 33). So 5 → 30.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 5, then multiply by 3 (4 → 27, 6 → 33, 7 → 36). So 3 → 24.
The same rule changes each first number into the second. Which number is missing?
The rule is: add 2, then multiply by 3 (6 → 24, 2 → 12, 7 → 27). So 9 → 33.
The same rule changes each first number into the second. Which number is missing?
The rule is: multiply the number by itself, then add 3 (3 → 12, 6 → 39, 4 → 19). So 5 → 28.
The same rule changes each first number into the second. Which number is missing?
The rule is: multiply the number by itself, then add 5 (3 → 14, 2 → 9, 6 → 41). So 5 → 30.
The same rule changes each first number into the second. Which number is missing?
The rule is: multiply the number by itself, then add 1 (9 → 82, 5 → 26, 8 → 65). So 6 → 37.
The same rule changes each first number into the second. Which number is missing?
The rule is: multiply the number by itself, then add 2 (8 → 66, 7 → 51, 5 → 27). So 3 → 11.
