Question

Which sequence is geometric and which is arithmetic?

Answer 1

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)

Answer 2

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.
