We know that sum of numbers
equal to multiple of 3 then the number is divisible by 3 then if
the same number is in decimal form than that number will also be
divisible by 3.

The first significant digit in any number must be 1, 2, 3, 4, 5, 6, 7, 8, or 9. It was discovered that first digits do not occur with equal frequency. Probabilities of occurrence to the first digit in a number are shown in the accompanying table. The probability distribution is now known as Benford's Law. For example, the following distribution represents the first digits in 194 allegedly fraudulent checks written to a bogus company by an employee attempting to...

(a) The harmonic series diverges very slowly. Prove that the sum of the first 106 terms is less than 15 and that the sum of the first 10° terms is less than 22. (You should not actually calculate these sums!) [2 marks] (b) Determine whether the series 10n +1 101 is convergent or divergent. [3 marks] (c) Consider the series whose terms are the reciprocals of the positive integers whose decimal represen-...

Banks issue credit cards with 16 digit numbers. If you've never thought about it before you may not realize it, but there are specific rules for what those numbers can be. For example, the first few digits of the number tell you what kind of card it is - all Visa cards start with 4, MasterCard numbers start with 51 through 55, American Express starts with 34 or 37, etc. Automated systems can use this number to tell which company...
