Which formula creates a series that doubles each value of [count] from the previous row?

The chosen formula correctly establishes a mechanism to create a series where each subsequent value doubles that of the preceding row's [count]. The logic behind this formula hinges on a couple of critical elements.

First, it checks if the value from the previous row ([Row-1:Count]) is zero. If it is zero, the formula returns 1. This is vital because it acts as a starting point for the series. When the sequence starts, it assigns the initial value as 1, which is the first value in this doubling sequence.

In scenarios where the previous row's count is not zero, the formula continues to double the value by multiplying it by 2. This results in a consistently doubling series – for example, if [Row-1:Count] were 1, the output would be 2; if it were 2, the output would be 4, and so on.

This formula successfully establishes a template that creates a geometric progression where each term is double the previous one, thereby fulfilling the requirement of the question.
