00:00 Find the sequence formula
00:03 Let's observe the number of squares in each term
00:21 Let's substitute the first term in equations and see if it fits
00:35 We can see that this formula doesn't fit
00:40 Let's continue with this method until we find the correct formula
00:51 This formula doesn't fit either
00:54 This formula fits the first term
00:59 And this formula also fits the first term
01:02 Let's check which formula also fits the second term
01:09 This formula doesn't fit the second term, so it's not the formula
01:23 And this is the solution to the question
