Generate and describe linear number sequences

What you'll learn

1. 1

   A linear number sequence is like a skipping rope — you jump the same amount each time!

2. 2

   What is the rule for this sequence: 3, 6, 9, 12, 15?

3. 3

   Jump along the number line to make the sequence: start at 2, add 4 each time. Land on the 4th number.

4. 4

   Let's find the 5th term of this sequence: start at 7, add 3 each time.

5. 5

   Now you try! Start at 10, add 6 each time. What is the 4th term?

6. 6

   A sequence starts at 4 and adds 5 each time. What is the 3rd term?

7. 7

   What is the rule for this sequence: 20, 17, 14, 11, 8?
