@CarterIndustries is that surposed to be a joke?

@Skua @Earthbenderrwefa @IStoleYourMeme @icecoldlava And his name is John Cena!!!!

@IStoleYourMeme whilst you're totally right, it actually doesn't change the answer from nineteen days. If the lily is 1 lake big on day 20, it was 0.6666... lakes big on day 19, and 0.4444... on day 18, so it still reached the halfway point on the 19th day

1 day

@IStoleYourMeme 7x8=56 and 14x4=56 so 7x8=14x4

Both ratios lead to different numbers. @Dullwolf

@IStoleYourMeme 7x8=14x4 no?

Alright, now moving on to the math @Dullwolf

@IStoleYourMeme sthop correctring thy grammaer

This was poorly worded. Half its size =/= 2x its size. EDIT: Ex. if the pond was 32m^2 large, and the lilypad grew half its size (1.5x) from 1m^2 every day, the sequence would be 1, 1.5, 2.25, 3.375, etc, rendering the answer and its reasoning untrue. If it went up by a common ratio of 2, meaning it grew 2x its size daily, it would go: 1, 2, 4, 6, 8, 16, 32, making the day before the last having half its size. There is no answer because there are no numbers in the sequence that are halves of each other.

@icecoldlava correct, now this thread has died, enjoy

Cuz if it's full size on day 20 then the day before it was half the size, the day before was day 19

@icecoldlava your reasoning?

19
