Well, isn't that a happy little mystery we have here, friend! Let's think about this together. Since the number is greater than 50 and has two digits, we can deduce that the number is 75. One digit is 5 and the other digit is half of 5, which is 2.5, but since we can't have a half digit, we round it up to 3. So Dan found the number 53.

Oh, dude, consecutive identical digits are just fancy words for when you have the same number back-to-back. Like when you see 22 or 777 in a row. It's not rocket science, just a fun little pattern that shows up in numbers.
When multiplying numbers with the same units digit, the units digit of the product is determined by the units digit of the base number raised to the power of the number of times it is being multiplied. In this case, since 7 is being multiplied 100 times, the units digit of the product will be the same as the units digit of 7^100. The units digit of 7^100 can be found by looking for a pattern in the units digits of powers of 7: 7^1 = 7, 7^2 = 49, 7^3 = 343, 7^4 = 2401, and so on. The pattern repeats every 4 powers, so the units digit of 7^100 will be the same as 7^4, which is 1. Therefore, the units digit of the product when one hundred 7's are multiplied is 1.

Let's denote the two digits as x and 2x, where x is the smaller digit. Since the number is odd, 2x must be an odd number, so x must be an even number. The only even number less than 5 that satisfies this condition is 2. Therefore, the number Dan found is 52.
Well, isn't that a happy little puzzle! Let's think about this together. Since the number is greater than 50 and has two digits, the only number that fits is 93. The digits are 9 and 3, with 3 being half of 9, and it's a lovely odd number!
The digits 0123456789, representing the numbers from 0 to 9, can be found in the decimal representation of pi. However, pi is an irrational number, meaning it has an infinite number of non-repeating digits. Therefore, while these digits do appear in pi, they occur in a seemingly random and unpredictable manner throughout its decimal expansion. As of now, no pattern has been discovered in the distribution of these digits within pi.

The first occurrence of the digit 0 in the digits of pi is at the 32nd decimal place.
4 options for the first digit, 3 options for the second digit, 2 options for the third digit. Multiply the number of options together, and you find how many 3-digit numbers you can get.
A four digit whole number can be found from 1000 to 9999
There are 9 pages that use a single digit (pages 1-9), leaving 495 digits - 9 pages × 1 digit/page = 486 digits There are 90 pages that use 2 digits (pages 10-99), leaving 486 digits - 90 pages × 2 digits/page = 306 digits There are 900 pages that use 3 digits (pages 100-999); this would be 2,700 digits, so the number of pages is somewhere in the hundreds. 306 digits ÷ 3 digits/page = 102 pages in the hundreds. → total number of pages = 102 + 90 + 9 = 201 pages.
