Question
Write six distinct integers whose sum is 7.
Solution
Let the six distinct integers be 1, 2, – 2, 3, – 3 and 6.
Now, sum of the above six distinct integers = 1 + 2 + (– 2) + 3 + (– 3) + 6
We can arrange the numbers, so that the positive integers and negative integers are grouped together.
We have, 1 + 2 + 3 + 6 + (– 2) + (– 3)
= 12 – 2 – 3
= 12 – 5
= 7
Hence, the required integers are 1, 2, – 2, 3, – 3 and 6.
Note: There are infinite combinations exist.
