MS Excel provides the default value for step in Fill Series dialog box

1 step value is correct, I say ............................B) is the answer

Data fill can be any sequence,1st quarter,1 years,1 months, etc.  by first entering the sequence, the block select the cells indicating the sequence, the "Data Fill Handle" double-click or drag.

B)1 - is the correct answer

A)0

I choose letter B for 1 dialog box
