You can only answer this question if you know how many numbers there were before.
(If you know how many were there after, then subtracting two gives you the number before).
So suppose there were n numbers with mean x. And you add two more numbers, a and b.
That means the sum of the n numbers was n*x.
Sum of the n+2 numbers is n*x + a + b
So the new mean is (n*x + a + b)/(n + 2)
