[Challenge] Array's and numbers

Question

Create a function which accepts a sorted array(by size) which is type double. and a number.
Then the function will check if any sum of 2 numbers from the array can create the number accepted by the function. if the duo exists the function will return True, otherwise it'll return false. And one last thing, only one iteration is allowed :)
Any language is allowed.
