The number is 56
23
The 2-digit number must be 20, because it is the only 2-digit number whose sum of its two even digits, 2 + 0 = 2, is greater than the product of its two even digits, 2 x 0 = 0. Moreover, 20 is a product of the two consecutive integers 4 and 5.
There is no pair of consecutive even integers whose sum is 264 - as their average is divisible by 4, that must mean that the sum of the unit digits of each of the pair of numbers could never be a multiple of 4 - which 264 is.
Consecutive identical digits could be digits that are the same and appear next to one another in a number. For example, the hundreds and tens digits in 1442 could be considered consecutive identical.
Integers of 6 digits are normally greater than integers of 5 digits
Well, 47 49 51 53 are four consecutive odd numbers those total squared has for identical digits. 40000.... The square root of any number that is only four digits long all containing the same digit has a value that is not an integer.
Yes: 1 and 0 are consecutive.
189743558134324259910593462 consists of 27 digits.
The longest string of consecutive numbers that are primes is two digits long, consisting of 2 and 3 only. There are no other consecutive numbers that are primes because no even numbers greater than 2 are primes.
Depends on where you start.
The sum of all the digits of all the positive integers that are less than 100 is 4,950.
There are 120 of them.
