Deep in a forgotten forest, Emek and Luna discovered an ancient gate guarding a hidden treasure chamber. The gate displayed a number pattern with missing carvings: 8, 16, 32, __, 128. They studied the sequence and noticed that each number was multiplied by 2 to create the next number. Emek and Luna predicted the missing number as 64 and explained the rule to the gate. The stones glowed, the gate opened, and the explorers continued their adventure toward the hidden treasure.

Hint
Look at how each number changes to become the next number.
The ancient gate shows the pattern 8, 16, 32, __, 128. What number completes the pattern?
48566472Correct! Each number is multiplied by 2, so 32 * 2 = 64.
Check the rule carefully. The numbers are doubled each time, not increased by the same amount.
Next🎉 Congrats! You got this question!
Hint
Continue the doubling rule after 128.
The gate pattern starts with 8 and each number is multiplied by 2. What is the sixth number in the pattern?
Correct! The sequence continues 8, 16, 32, 64, 128, 256.
Continue multiplying each number by 2 until you reach the sixth position.

Hint
A correct pattern must follow the same rule between every pair of numbers.
A traveler says the missing number in the gate pattern should be 96 because the numbers are getting larger. What is the best reason this is incorrect?
The pattern needs a repeated rule, and 96 does not follow multiplying by 2The pattern should always use addition instead of multiplicationThe first number in the pattern should be changedThe largest number in a pattern must always be 100Correct! The rule is multiplying by 2, and 96 does not fit that rule.
A number pattern must follow the same rule throughout the sequence.
