WAP in Java<\/em> to input a number and check whether it is a Pronic Number<\/em> or Heteromecic Number or not<\/p>\n\n\n\n

A pronic number is a number which is the product of two consecutive integers, that is, a number of the form n(n + 1)<\/strong>. The pronic number<\/a> is also called oblong numbers, heteromecic numbers, or rectangular numbers.<\/strong>The first few Pronic numbers are::- 0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, 156, 182, 210, 240, 272, 306, 342<\/p>\n\n\n\n

Example:<\/p>\n\n\n\n

30 = 5 * (5+1)
42 = 6 * (6+1)
56 = 7 * (7+1)<\/p>\n\n\n\n
