Trick 4: Think of a number Ask someone to pick a number. Add the next higher number to it. Add 9 and divide by 2, and then subtract the original number. The answer will be 5.
1089 is widely used in magic tricks because it can be "produced" from any two three-digit numbers. This allows it to be used as the basis for a Magician's Choice.
The mystery is this: first, take any three digit number, where the first and last digits differ by two or more and reverse the number to produce a new one. Then subtract the smaller from the larger producing another new number. If you reverse this number and this time add the two, the result will always be 1089.
Kaprekar constant, or 6174, is a constant that arises when we take a 4-digit integer, form the largest and smallest numbers from its digits, and then subtract these two numbers. Continuing with this process of forming and subtracting, we will always arrive at the number 6174.
A permutation of the digits in 142857 is produced when you multiply it by any number from 1 to 6, making it cyclic. For instance, multiplying 142857 by two yields 285714, and by five yields 714285.
If you multiply 7 x 11 x 13 you get 1001 and if you take 1001 times any three- digit number you get a six-digit number where the original three-digit number repeats. Therefore, your original six-digit number would be divisible by 1001 or 7, 11, and 13.
Hence, “58” will be the next term. AP Police Constable SPET Postponed!
Trick 3: Think of a number
Subtract 3 with the result. Divide the result by 2. Subtract the number with the first number started with. The answer will always be 3.
What Is the Rule of 72? The Rule of 72 is a simple way to determine how long an investment will take to double given a fixed annual rate of interest. Dividing 72 by the annual rate of return gives investors a rough estimate of how many years it will take for the initial investment to duplicate itself.
To physicists, 137 is the approximate denominator of the fine-structure constant (1/137.03599913), the measure of the strength of the electromagnetic force that controls how charged elementary particles such as the electron and muon interact with photons of light, according to the National Institute of Standards and ...
In mathematics 9 is a composite lucky number and its divisors are 1 and 3. It is a square of the third natural number and it's a third perfect square number in the number system. It is the first composite odd number which is the only single digit. It is a divine and the heavenly number present in the universe.
123 + 4 - 5 + 67 - 89 = 100.
Here are the rules: use every digit in order - 123456789 - and insert as many addition and subtraction signs as you need so that the total is 100. Remember the order of operations!
Detailed Solution
Given series: 1, 4, 9, 25, ? Pattern: The given series is a square of natural numbers. Hence, 36 is correct.
As the obtained number is "40". Therefore, the correct answer should be "Option 4: 40".
58 is correct answer.
A prime number is a number that can only be divided by itself and 1 without remainders. What are the prime numbers from 1 to 100? The prime numbers from 1 to 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
The number 6174 is known as Kaprekar's constant after the Indian mathematician D. R. Kaprekar.
The multiples of 222 are 222 × 1 = 222, 222 × 2 = 444, 222 × 3 = 666, 222 × 4 = 888, 222 × 5 = 1110, . . . . . . . . . 222 × 12 = 2664, 222 × 13 = 2886, 222 × 14 = 3108, 222 × 15 = 3330, . . . . . . . . . and so on.
There are mostly natural numbers which cannot be distinguished from each other. They are inaccessible; we briefly call them dark. It is unfamiliar and hard for mathematicians trained to believe in completed infinity to imagine a. potentially infinite set which is finite without having a last fixed element.
