The table contains a sequence with missing terms. List the missing terms if the sequence is arithmetic.

Answer explanation

Use the slope formula on arithmetic sequences when you are missing numbers. Use the two points you have (1, 3) and (5, 243). The slope tells you what is being added and subtracted each time. The add that number to 3 for the next number and so on.

The table contains a sequence with missing terms. List the missing terms if the sequence is geometric.

Answer explanation

With Geometric sequences you must figure out what you would have to multiply by to get the last number. You will have to multiply it for each missing space.
