Examples include the seven days of creation and so seven days that make up a week, and the seven lamps on the Temple Menorah. One variation on the use of seven is the use of the number six in numerology, used as a final hallmark in a series leading to a seven (e.g. mankind is created on the sixth day in Genesis, out of the seven days of creation).
A pronic number is a number that is the product of two consecutive integers, that is, a number of the form (+). [1] The study of these numbers dates back to Aristotle.They are also called oblong numbers, heteromecic numbers, [2] or rectangular numbers; [3] however, the term "rectangular number" has also been applied to the composite numbers.
A number n that has more divisors than any x < n is a highly composite number (though the first two such numbers are 1 and 2). Composite numbers have also been called "rectangular numbers", but that name can also refer to the pronic numbers, numbers that are the product of two consecutive integers.
Seventy-two is a pronic number, as it is the product of 8 and 9. [1] It is the smallest Achilles number, as it's a powerful number that is not itself a power. [2] 72 is an abundant number. [3] With exactly twelve positive divisors, including 12 (one of only two sublime numbers), [4] 72 is also the twelfth member in the sequence of refactorable ...
42 is a pronic number, [1] an abundant number [2] as well as a highly abundant number, [3] a practical number, [4] an admirable number, [5] and a Catalan number. [6]The 42-sided tetracontadigon is the largest such regular polygon that can only tile a vertex alongside other regular polygons, without tiling the plane.
with π (x) being the number of prime numbers less than or equal to x. The end points of these two ranges are a square between two pronic numbers, with each of the pronic numbers being twice a pair triangular number. The sum of the pair of triangular numbers is the square.
Panin's conversion occurred in 1890 when his attention was caught by the first chapter of John, in which the article ("the") is used before "God" in one instance, and left out in the next: "and the Word was with the God, and the Word was God." He began to examine the text to see if there was an underlying pattern contributing to this peculiarity.
30 is a square pyramidal number. 30 is an even , composite , pronic number . With 2 , 3 , and 5 as its prime factors , it is a regular number and the first sphenic number , the smallest of the form 2 × 3 × r {\displaystyle 2\times 3\times r} , where r is a prime greater than 3.
