Utter nonsense!
Given any set of n numbers, it is ALWAYS possible to find a polynomial of degree (n-1) such that the polynomial generates those numbers.
In this case, try
Un = (19n4 - 270n3 + 1373n2 - 2826n + 2064)/24 for n = 1, 2, 3, 4 etc.
Yes, it is the 13th triangle number (13 levels from 1 to 13 dots).
There is no single solution for x2 + y2 = 13, as there are an infinite number of corresponding values that could be plugged in for x and y. x2 + y2 = 13 is a function that describes a circle. The circle would have a center point of 0, 0, and a radius of √13.
The answer depends on the units used for 13 and 16.
* (n-2)180 * n = number of sides of the polygon * (15 - 2)180 * (13)180 * = 2340o
The formula for number of sides a polygon has given the sum of its internal angles is 1800 * (n - 2). So, for a triangle, n=3, and sum of the angles is 1800. So to answer your question, first divide 1,980 by 180 to get 11. Now add 2, and you get the number of sides, 13. In case you're curious, a 13 sided polygon is called a triskaidecagon.
The numbers that belong to the series are the following: 1, 2, 5, 10, 13, 26, 29 and 48.
1 - it is the only number that is neither prime nor composite.
9 - all the rest are prime
Numerical Answer48 does not belong, because the sequence is (double) then (add 3) and after 256 to 29, the last number should be 58.Spelling Answer2 does not belong, because the rest of the numbers include the letter E when you spell them out in English.
The answer is 12 every other numbers are odd numbers, but 12 is an even number
Most probably 48.
2
It could be any one of them. 5: The smallest prime number with a composite on either side. 2: The only even prime number. 8: The only perfect cube number. 13: The only 2-digit prime. 16: The only perfect square number.
17 :)
21. This is the Fibonacci series.
The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.
Each one of them. 15: the only semi-prime in the list 2: the only even prime in the list 8: the only perfect cube in the list 13: the only odd prime in the list 16: the only perfect square in the list. Take your pick!
