Which sequence is geometric and which is arithmetic?

The table on the left is arithmetic
This is because each term is increasing by the same amount (2) each time.
--------------------------------------------
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.
Both involve the number 2, but the first table uses addition while the second table uses multiplication.
1) Arithmetic
~3,5,7
common difference of 2
2)Geometric
~3,6,12
each term is found by multiplying the previous one by a fixed number
Hopefully this helped- have a good day)
