next place The cog T count on a vertical side, chainring on top of a grid .. plug in the numbers

Draw a zigzag line between them as the Ratio values are closer to each other .. and there is your sequence

visual.. tape it to your bike..

BITD we had half step gearing... middle & large chain ring close together in size, so gear sequence alternated between them..
'granny' took up at the bottom end..

Brompton 6 speed uses 2 cogs half stepping .. a wider ratio 3 speed hub.. now..


_________________________________

In the 50's I put together a 3 speed hub, with 3 cogs and a triple chainring crankset

now the crank can be another internal gear .. rear internal gear hub's engineers sort out the sequence for you..

Like that dual range German 7 speed hub.... for 14 speeds all in a row..
