The numbers that can be arranged to form a rectangle are called Rectangular Numbers (also known as Pronic numbers). The first few rectangular numbers are: 0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, 156, 182, 210, 240, 272, 306, 342, 380, 420, 462 . . . . . . Given a number n, find n-th rectangular number.

FIRST 10 RECTANGULAR NUMBERS ARE

0, 2, 6, 12, 20, 30, 42, 56, 72, 90, etc.

By using Rn=n(n+1) (or) Rn=n^2+n

Ex: Rn=2(2+1) (or) Rn=2^2+2

Rn=6. Rn=6

Ex:Rn=3(3+1) (or) Rn= 3^2+3

Rn=12. Rn=12

Like this you can the all values.
