The table on the left is arithmetic
This is because each term is increasing by the same amount (2) each time.
- 3+2 = 5
- 5+2 = 7
- 7+2 = 9
- 9+2 = 11
--------------------------------------------
The table on the right is geometric
Why? Because this time we are multiplying each term by the same value (2) to get the next term.
- 3*2 = 6
- 6*2 = 12
- 12*2 = 24
- 24*2 = 48
Both involve the number 2, but the first table uses addition while the second table uses multiplication.
