Question

Below is a sequence represented by squares. How many squares will there be in the 6th element?

Video Solution

Solution Steps

00:00 Find the 6th term
00:04 Let's count the squares in each term
00:26 We can see that the number of squares equals the term's position squared
00:33 Therefore, we can conclude this is the sequence formula
00:40 Let's substitute the corresponding term position and calculate
00:45 And this is the solution to the question

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.

Answer

36
