Four arithmetic sequences are shown.

How do their common differences compare? Place them in order of the common difference from LEAST to GREATEST

Four geometric sequences are given.

How do their ratios compare? Place them in order from LEAST common ratio to GREATEST common ratio.

Write an equation that models the sequence shown in the table. Simplify.

If you use the 0th term in the equation, then you should use only n in the exponent.

If you use the 1st term in the equation, then you should use (n-1) in the exponent.

The figure below shows the number of dots in each of the first three terms of a pattern.

Determine the sequence for this pattern. How many dots would there be in the 10th term?
