Question

Use the following sequence. 3, 6, 12, 24, 48.

1) Mr. Brust says that the 10th term of the above sequence is 768. Is he right? How do you know?

Answer 1

No, Mr. Brust is not right. The 10th term in the sequence is 1536. I know this because each number is double the previous. So, if I work out the sequence up to the 10th term, I get 1536
