format sequence list ( apple Numbers Question )

It will only do that for sequences that Numbers is programmed to recognize (days of week, numeric sequences, and whatever else). For others, you have to select all the cells in the pattern before you drag down.

If you have Red, Green, and Blue in three cells in a column, select all three then drag down. But if Numbers sees a numeric pattern like A1, A2, A3, it will continue to increment the number instead of repeating the pattern. For that, you would have to enter the pattern twice, select all six cells, then fill down.

The answer you are looking for is yes but, unfortunately, the answer to the question is no. Numbers does not have it.
