Answer:
46
Step-by-step explanation:
Let <em>a to d</em> be <em>number 1 to 4</em> respectively.
15 = (a + b + c + d) / 4
(a + b + c + d) = 60 ------> <em>total sum of the 4 numbers</em>
Since the sum of 3 numbers (assuming a to c) is 14,
Fourth number (d) = 60 - 14
= 46
That's how I would do it, hope this helps :)
