Tell me if im wrong thank you!

Im like 90% sure

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

3, 12, 48, 384, 1536, 6144, 24576, 98304
