The 7 divisibility rule is a simple yet powerful tool for determining whether a number is divisible by 7. To apply the rule, you need to double the last digit of the number and subtract the result from the remaining part of the number. If the result is divisible by 7, then the original number is also divisible by 7. For example, consider the number 14. The last digit is 4, so doubling it gives 8. Subtracting 8 from 14 results in 6, which is not divisible by 7. However, if we try the number 21, the last digit is 1, so doubling it gives 2. Subtracting 2 from 21 results in 19, which is not divisible by 7. But if we try the number 28, the last digit is 8, so doubling it gives 16. Subtracting 16 from 28 results in 12, which is divisible by 7.
