What are Oblong numbers?
An oblong number (also called a "pronic number") represents an oblong shape created when dots are placed equidistant from each other in rows and columns. The number of dots across must be one number greater than the number of dots down, so if I make a grid of dots which is 3 dots across and two dots down, it represents the number 6, the total number of dots. Six, then, is the oblong number. If the oblong has 4 dots across and 3 dots down, it equals 12 dots, so the oblong number is 12.. . . .. . . . = 12 This visual representation of a number is called an "array.". . . .These arrays are used commonly now in schools to help students understand the concept of multiplication. In this case, (3X4=12).The algebraic formula for such a number is: n(n+1). This is an integer (number) times the same number plus one. So 3 X (3=1), or four, equals 12.The first few oblong numbers are 2, 6, 12, 20, and 30. This series of numbers is the successive sums of the series of even numbers or the products of two consecutive numbers: 2 = 1·2; 6 = 2·3 = 2 + 4; 12 = 3·4; and so on.
