Welcome to Nikonians

Successive f/stop values do indeed represent a halving (or doubling) of the area of the lens' diaphragm opening, and therefore a corresponding difference in the amount of light transmitted. That's assuming that the lens is correctly adjusted, of course

The standard numbering sequence is:

1 - 1.4 - 2 - 2.8 - 4 - 5.6 - 8 - 11 - 16 - 22 - 32 - 45

The "odd" numbers in the sequence (1.4, 2.8...) have always been rounded for convenience.
