Which sequence is geometric and which is arithmetic?
tekilochka [14]

The table on the left is <u>arithmetic</u>

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 <u>geometric</u>

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.
