The .collect method aint working properly can someone help me?

fibs = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55]

Add your code below!

doubled_fibs = fibs.collect { |p| puts p * 2 }

it wants every number doubled and i thought i did it right but code academy tells me the doubled fibs array should include 2. heres the link

Get rid of puts. This is because puts just prints to the screen and returns nil. So you end up with an array of just nil.

fibs = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55]
doubled_fibs = fibs.collect { |p| p * 2 }
