Explanation

To complete the sequence, we need to identify the pattern:

The given sequence is: __, 56, 28, 14, 7

Observing the sequence, each number is half of the previous one:

56 ÷ 2 = 28

28 ÷ 2 = 14

14 ÷ 2 = 7

So, to find the number before 56, we double 56:

56 × 2 = 112

Therefore, the complete sequence is:

112, 56, 28, 14, 7
