Can you solve this puzzle?

Do you enjoy solving puzzles that appear online especially tricky math questions? If yes, this number puzzle is a simple way to test your thinking skills.

Look at the numbers in the image and find the missing number in the middle row. The first row contains 83, 11 and 2. The second row has 79, ? and 7, while the last row contains 68, 14 and 5.

So what number should replace the question mark?

The pattern becomes clear when you look at how the numbers in each row are connected.

In the first row add the digits of 83:

8 + 3 = 11

Then add the digits of 11:

1 + 1 = 2

The same pattern appears in the last row:

6 + 8 = 14

Then:

1 + 4 = 5

Now apply the same rule to the second row. Start with 79:

7 + 9 = 16

Then:

1 + 6 = 7

This matches the final number in the row.

Therefore the missing number is 16.
