A sequence of numbers follows this rule: Multiply the previous number by -2 and add 3. The fourth term in the sequence is -7.

1. Give the next 3 terms in the sequence.
2. Give the 3 terms that came before -7 in the sequence.

A sequence starts 0, 5, . . .

1. Give a rule the sequence could follow, and list the next 3 terms for that rule.
2. Give a different rule the sequence could follow, and list the next 3 terms for that rule.
