Anonymous function

Rewatched the previous video, like, 10 times but still can’t get through this Quiz Question. It seems like I’ve tried every possible option but my answer is still incorrect :–(

This is the question I don’t know the answer to: Let’s apply our anonymous function. We have an array of integers called numbers, let’s use our anonymous function on numbers.

val numbers = Array(5, 10, 15, 20, 25)

val result = numbers.___((x: Int)___ x + 10)

(my answer to the second question in this quiz is correct)
