To solve this number puzzle, look for any relation of the numbers. Check if there is a possible relation of adjacent numbers, etc.

In this puzzle, the numbers in the first column are consecutive numbers. For the second column, notice that 3 is next to 1 and 2 in the first column. The number 3 is also the sum of 1 and 2. If you check the next number in the second column, 5 is the sum of 2 and 3 in the first column. You may continue checking for the pattern. Make sure that the pattern applies to all the numbers.
