Question

Determine if the sequence below is arithmetic or geometric and determine the

common difference / ratio in simplest form.
1, 3, 5, ...

Answer 1

Arithmetic: uses properties of addition
Geometric: uses properties of multiplication

1 + 2 = 3 + 2 = 5
This sequence is Arithmetic

Arithmetic uses common different: how much the number goes up by each time; rate of change

The common difference is 2

Answer 2

it is an arithmetic sequence, common difference is 2
