Here is a rule to make a list of numbers: Each number is the sum of the previous two numbers. Start with the numbers 0 and 1, then follow the rule to build a sequence of 10 numbers.

• 0, 1, 1, 2, 3, 5, 8, 13, 21, 34

• 0, 1, 1, 3, 5, 8, 13, 21, 34

• 0, 1, 1, 2, 5, 8, 13, 21

A sequence of numbers follows the rule: multiply the previous number by -2 and add 3. The fourth term in the sequence is -7. Give the 3 terms that came before -7 in the sequence.

• 1. 17, -31, 65

• 1. 2, -1, 5

• -2,1,5

• 1. 17, 31, 65

Here are the first two terms of a geometric sequence: 2, 4. What are the next three terms?

• 1. 
     8, 16, 32

• 1. 
     18, 54, 162

• 10, 26, 74

• 1. 17, 31, 65

What is the growth factor of the geometric sequence 18, 54, 162?
