I have to write expressions for patterns.
example:
Pattern: 8, 13, 18, 23, 18, 33
Description: Start at 8 then add 5.
Expression: n5+3
There are two patterns that I couldn't figure out, and nither could my teacher when I asked her.
1.
Pattern: 3, 6, 10, 15, 21
Description: Start at 3, then add 3, next add 4 and so on and so forth.
Expression: ???
2.
Pattern: 8, 16, 32, 64, 128
Description: Start at 8, then multiply by 2.
Expression: ???
Please help.
