Complete the pattern.2.78, 4.03, 5.78, 8.03, 10.

The next number in the pattern would be 14.03.

To find this, note the differences found by subtracting each number from the number that comes after.

4.03 - 2.78 = 1.25

5.78 - 4.03 = 1.75

8.03 - 5.78 = 2.25

10.78 - 8.03 = 2.75

Since each difference goes up by .5 each time, we know we can add .5 to the last difference to find the newest one.

2.75 + .5 = 3.25

Now we have the difference, so we add that to the last number.

10.78 + 3.25 = 14.03
