It is easy to find a rule based on a polynomial of order 6 such that the first six numbers are as listed in the question followed by the chosen next number. There are also non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one.The simplest rule, based on a polynomial of order 5 isU(n) = (24*n^5 - 595*n^4 + 5310*n^3 - 21185-n^2 + 36726*n - 19920)/120 for n = 1, 2, 3, ...

What is the pattern rule for this pattern 1-3-6-10-15-21?
The pattern follows a sequence of triangular numbers. Each number in the sequence is derived by adding consecutive integers: 1 (1), 1 + 2 (3), 1 + 2 + 3 (6), 1 + 2 + 3 + 4 (10), and so on. Therefore, the next number in the sequence can be found by adding 5 to the previous number, resulting in 21 + 6 = 28.
What number goes into 21 and 33?
The numbers 1 and 3.
What is the pattern of these numbers '1 1 2 3 5 8 13 21'?
Each new number in the series is the sum of the previous two numbers. That sequence is part of an infinite series called the Fibonacci series.
Are prime numbers same as odd numbers?
No.Prime numbers are numbers that can only be divided evenly by itself and 1.For example, the number 7 can only be divided by 7 and 1.Odd numbers are numbers that end in (or are) 1, 3, 5, 7, or 9.For example, the number 21 is odd since it ends in a 1, but it is not prime because itcan be divided by 1, 21, 7, and 3. (7 times 3 = 21.)2 is a prime number and is even not odd - it is the only even prime number.
Is the numbers 19 21 and 23 a composite number?
No, the numbers 19, 21, and 23 are not composite numbers. A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In the case of these numbers, 19 and 23 are prime numbers because they are only divisible by 1 and themselves, while 21 is a composite number because it has divisors other than 1 and itself (3 and 7).
What number goes into 21 and 100?
1. The two numbers are coprime.
What number goes into 29 and 21?
1. The two numbers are coprime.
Is 21 a natural number?
Yes, 21 is a natural number. Natural numbers are the set of positive integers starting from 1, and they include all whole numbers like 1, 2, 3, and so on. Since 21 is a positive integer, it qualifies as a natural number.
What are 21's composite numbers?
The factors of 21 are 1, 3, 7, and 21. The only factor of 21 that is a composite number is 21.
