Question

After a gas-filled balloon is released, it rises 90 feet by the end of the first minute. By the end of the second minute, the balloon rises 120 feet, and by the end of the third minute, it rises 150 feet. How many feet would the balloon rise in 8 minutes?
a 300
b 330
c 390
d 660

Answer 1

nevermind i got it lol

Answer 2

the answer is A 300

Answer 3

I'd go with A) 300. There's an initial jump from 0-90, but from there it seems to steadily climb by 30 feet per minute. Using that information, you make your way up to the 8th time.
