What is the missing number in the sequence: 5, 10, 20, ?, 80 (2021)

Step 1: Look at the sequence of numbers: 5, 10, 20, ?, 80.
Step 2: Identify the pattern by checking how each number relates to the next one.
Step 3: Notice that 10 is double 5 (5 * 2 = 10).
Step 4: Notice that 20 is double 10 (10 * 2 = 20).
Step 5: To find the missing number, multiply 20 by 2 (20 * 2).
Step 6: Calculate 20 * 2, which equals 40.
Step 7: Now check the next number: 40 * 2 should equal 80.
Step 8: Since 40 * 2 = 80, the pattern is confirmed.
