00:00Welcome everyone. So yes, a lot of people thought that the answer for this one was supposed to be 20.
00:05Because see 2 and 5 the difference is 3. Here the difference is 6. So next difference should have been 9.
00:12And then after that the difference should have been 12, right?
00:14But if I do 9, 11 plus 9 the answer comes out to be 20.
00:19But 20 plus 12 is not equal to 23.
00:25So obviously there is some other logic which is going to be working for this particular question.
00:30So in this case what we should do?
00:31If you look at all of these numbers, all of these numbers are basically what they are basically primes.
00:39Okay, if you look at it consciously the numbers are primes.
00:42So what is the prime number which happens to come after 2 that is 3.
00:46But here we have skipped one prime number and the next prime number is 5.
00:51The prime number which comes after 5 which is 7 and then after that the next prime number is 11.
00:56So again basically looks like we are skipping one prime numbers.
00:59So after 11, what is the next prime number which comes out to be 13.
01:03So after 13, the next prime number should have been 17.
01:08And after 17, the next prime number is 19 which is skipped.
01:12And after that the next prime number which follows is 23.
01:16So here we can say the answer for this particular question mark is supposed to be 17.
01:22I hope this is very very clear to everyone.
01:26That's it for today.
01:27I will see you in the next video.
