Explain whether the following sequence is arithmetic, geometric or neither. If possible, find the common difference, d, or the common ratio, r

7, 12, 17, 22, 27, ...

• Because there is a common difference of

  d=5, the sequence is arithmetic.

• Because there is a common ratio of

  r=5, the sequence is geometric.

• Because there is no common difference or common ratio it is neither.
