Arithmetic sequences have a common difference between consecutive terms. therefore, they’re modeled with functions.
geometric sequences have a common ratio between consecutive terms. therefore, they’re modeled with functions.

Linear functions.

Exponential functions.

Step-by-step explanation:

An example of an arithmetic sequence is  1, 3, 5, 7, common difference is 2 and is modelled by the linear function

1 + 2(n -1).

A geometric sequence might be  2, 4, 8, 16  where  there is a common ratio of 2 and is modelled by 2.(2)^n-1).

yes. we do proportions in probabilities.

1/3 + 1/5 = 8/15.
