input: Write a python function to find the closest match to a given number from a list of numbers.
  assert closest_match([1, 5, 9, 15], 8) == 9
  assert closest_match([2, 4, 6, 8], 5) == 4
  assert closest_match([-2, -1, 1, 2], -1.5) == -1
output: def closest_match(numbers, target):
      return min(numbers, key=lambda x: abs(x - target))
