92 is a pentagonal number. The test for a pentagonal numer is as follows.

   n = (sqrt(24x + 1) + 1) / 6

   if 'n' is a natural number, then 'x' is pentagonal;
   otherwise, 'x' is not pentagonal

   test if 92 is pentagonal...

   n = (sqrt(24(92) + 1) + 1) / 6
   n = (sqrt(2208  + 1) + 1) / 6
   n = (sqrt(2209) + 1) / 6
   n = (47 + 1) / 6
   n = 48 / 6
   n = 8

   8 is a natural number; therefore, 92 is pentagonal

The sequence of pentagonal number is calculated as follows.

   pn = (n(3(n) - 1)) / 2, where n ≥ 1

   p1 = (1(3(1) - 1)) / 2 = 1
   p2 = (2(3(2) - 1)) / 2 = 5
   p3 = (3(3(3) - 1)) / 2 = 12
   ...
   p8 = (8(3(8) - 1)) / 2 = 92
