GCSE Secondary Maths Age 13-17 - Algebra: Sequences - Explained

The video tutorial explains how to identify and work with arithmetic sequences. It begins by introducing the concept of arithmetic sequences and how to recognize the pattern of adding a constant number. The tutorial then guides viewers through deriving the expression for the Nth term of the sequence. Finally, it demonstrates how to determine if a specific number is part of the sequence using the derived expression.

What is the common difference in the arithmetic sequence discussed in the video?

• 6

• 4

• 8

• 2

How is the Nth term of the sequence expressed in terms of N?

• 4N + 2

• 2N - 4

• 4N - 2

• 2N + 4

What is the relationship between the sequence and the four times table?

• The sequence is the four times table plus 2

• The sequence is the four times table minus 2

• The sequence is the four times table plus 4

• The sequence is the four times table minus 4

How do you determine if 86 is a term in the sequence?

• By checking if 86 is divisible by 4

• By adding 86 to the sequence

• By subtracting 86 from the sequence

• By solving the equation 4N - 2 = 86

What is the value of N when 86 is a term in the sequence?

• 22

• 23

• 21

• 20
