00:06 Let's find the sixth term in the sequence.
00:10 First, let's count the number of squares in each term.
00:20 Notice, the number of squares equals the term's position, raised to the power of two.
00:32 So, we can conclude that this is the formula for the sequence.
00:39 Now, substitute the term's position to calculate its value.
00:46 And that's how we find the solution to this problem.

Step-by-step solution

To solve this problem, we'll follow these steps:

  • Identify the sequence pattern: it follows perfect squares.
  • Associate each step with its corresponding perfect square number.
  • Calculate the 6th element's number of squares using the formula n2n^2.

Now, let's work through each step:
Step 1: The sequence is defined by the perfect square numbers: 12,22,32,1^2, 2^2, 3^2, \ldots.
Step 2: Each element in this sequence corresponds to an integer squared, revealing the sequence as 1,4,9,16,25,1, 4, 9, 16, 25, \ldots.
Step 3: For the 6th element, calculate 626^2:
62=366^2 = 36

Therefore, the solution to the problem is 36.
