00:00Welcome everyone. So yes, a lot of people thought that the answer for this one should be 64.
00:07Because here, if you look closely, all of these are squares, right?
00:11This is 2 square, this is 3 square, this is 5 square.
00:17So next they thought, because here the difference is of 1, here the difference is of 2,
00:21the next difference should have been of 3, which gets you 8 square.
00:25And 8 square's answer is what? 64.
00:27But, if you look closely, the difference between 8 and this is 11 square, right?
00:33So here also difference comes out to be 3.
00:35So that means that this logic will not work, because here technically the difference should have been of 4.
00:44Right? So probably that is not going to work.
00:47So now in this case, how will we do this?
00:50Okay? See, here you need to realize that, see, this one is 11 square.
00:56So these are what prime numbers?
00:592, 3, 5, then 11.
01:01So here the prime number which comes between 5 and 11 is 7.
01:07So 7 square.
01:08So answer for this question mark has to be 49.
01:13I hope this is very, very clear to everyone.
01:16That's it for today.
01:18I will see you in the next video.
