(mathematics) Of a number which is the product of two consecutive integers
*1478 - Pierpaolo Muscharello, Algorismus'' p.163.Jens Høyrup,
*:Pronic' root is as if you say, 9 times 9 makes 81. And now take the root of 9, which is 3, and this 3 is added above 81: it makes 84, so that the ' pronic root of 84 is said to be 3.
*1794 - David Wilkie,
*:When a'' = 2, and ''d'' = 2 also, in this case, in equation 1st, ''s''=''n''2 + ''n'' = ''a'' pronic''' number, which is produced by the addition of even numbers in an arithmetic progression beginning at 2; and the ' pronic root .
*1804' - Paul Deighan,
*:As I admire each proposition fair,
*:the pronic number and the perfect square,
*:the puzzling intricate equation solv'd,
*:as Grecia's chief the Gordian knot dissolv'd;
*:: - John Bartley
*1814 - Charles Butler,
*:A pronic' number is that which is equal to the sum of a square number and its root. Thus, 6, 12, 20, 30, &c. are ' pronic numbers.
*1998 - Wayne L. McDaniel,
*:It may be noted that if L''n is a pronic number, then ''L n is two times a triangular number.
*2005' - G. K. Panda1 and P. K. Ray,
*:Thus, our search for cobalancing number is confined to the pronic' triangular numbers, that is, triangular numbers that are also ' pronic numbers.
