Come back tomorrow for the correct answer to this teaser.
Answer for yesterday's Brain Teaser
There is an integer which shows a very peculiar feature: no matter any number is subtracted from it, the result is always exactly divisible by successor of that number. What is the integer?
The integer is −1.
For instance, if 4 is subtracted from −1, then we get (−1) − 4 = −5, which is divisible by 5 (one more than 4).
If 9 is subtracted from −1, then we get (−1) − 9 = −10, which is divisible by 10 (one more than 9).
