1. 0:00Let's solve an interesting puzzle. Look
2. 0:02at the sequence carefully and try to
3. 0:04find the missing number.
4. 0:06Pause the video for a moment, work it
5. 0:09out yourself, and see if you can
6. 0:11identify the correct option.
7. 0:13The key to solving these questions is to
8. 0:16find the rule that connects each number
9. 0:19to the next.
10. 0:20Whenever you see a number sequence,
11. 0:22remember that there must be some pattern
12. 0:25connecting the terms. Here, we have 2 2
13. 0:294 12 48 and then a question mark. Our
14. 0:33job is to figure out how each number is
15. 0:36changing as we move from left to right.
16. 0:40Once we discover that rule, finding the
17. 0:42missing number becomes much easier.
18. 0:45Let's examine the sequence step by step.
19. 0:48The first two is multiplied by one,
20. 0:50which gives two. Next, two is multiplied
21. 0:54by two, giving four. Then, four is
22. 0:57multiplied by three, giving 12. After
23. 1:01that, 12 is multiplied by four, giving
24. 1:0448. Do you notice the pattern? The
25. 1:07numbers are being multiplied by
26. 1:09consecutive integers, 1 2 3 and 4. Now,
27. 1:14the rule should be clear. The next step
28. 1:17is to multiply 48 by five. So, we need
29. 1:21to calculate 48 multiplied by five,
30. 1:24which equals 240.
31. 1:27Therefore, the missing number is 240,
32. 1:30option C.
33. 1:32Did you get the answer right? Let me
34. 1:34know in the comments and I'll see you in
35. 1:36the next video.
