Step-by-Step Explanation:


To find the missing number in the given sequence, let us analyze the mathematical relationship between consecutive terms.


Given sequence: 24, 120, 720, 5040, 40320, _____


Let us look at the pattern of multiplication between each term:


1st term to 2nd term:

24×5=120


2nd term to 3rd term:

120×6=720


3rd term to 4th term:

720×7=5040


4th term to 5th term:

5040×8=40320


We can observe a clear pattern where each successive term is obtained by multiplying the preceding term by consecutive integers starting from 5 (i.e., × 5, × 6, × 7, × 8, ...).


Following this logical pattern, the next term must be obtained by multiplying the 5th term by 9:


40320×9=362880


Thus, the number that logically completes the sequence is 362880.
