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

The video tutorial explains how to identify and extend a sequence by adding a constant number to each term. It demonstrates finding the next term in a sequence by adding 7 to the previous term and explains the method used. The tutorial also covers calculating the 10th term in the sequence by repeatedly adding 7, resulting in a final answer of 65.

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

• 7

• 8

• 6

• 5

If the sequence starts with 2 and each term increases by 7, what is the fourth term?

• 16

• 30

• 37

• 23

How do you find the next term in an arithmetic sequence?

• Divide the last term by 2

• Multiply the last term by 2

• Add the common difference to the last term

• Subtract the common difference from the last term

What is the 10th term of the sequence starting with 2 and increasing by 7 each time?

• 64

• 65

• 59

• 58

Which of the following sequences is an arithmetic sequence?

• 3, 6, 9, 12

• 1, 2, 4, 8

• 2, 4, 8, 16

• 5, 10, 20, 40
