Learn how to determine the rule given the first five terms of a sequence

The video tutorial guides students through solving a number sequence problem. Initially, the teacher explores different methods, including multiplication, to find a formula. After testing and evaluating these methods, the teacher demonstrates that subtracting 4 from the sequence number yields the correct formula. The tutorial emphasizes the importance of trial and error in problem-solving and concludes with the application of the discovered formula.

What was the initial approach to find the pattern in the sequence?

• Multiplying each number by -3

• Adding 4 to each number

• Subtracting 2 from each number

• Dividing each number by 2

Why is it important to try different methods when solving a problem?

• It helps to confirm the first method is correct

• It allows for finding the most complex solution

• It ensures that all possible solutions are considered

• It makes the problem more difficult

Which operation was finally used to find the correct pattern?

• Multiplying by 3

• Adding 4

• Dividing by 2

• Subtracting 4

What does the correct formula n - 4 represent in the sequence?

• Multiplying each term by 4

• Adding 4 to each term

• Subtracting 4 from each term

• Dividing each term by 4

What is the result of applying the correct formula to the number 2?

• -3

• 0

• -1

• -2
