83

79       89    97..........like that.........4 primes, in a 3 sided figure.......4 and 3, 43, 14th prime, 14.13i.......0.13i.......1/3, 1st to infinity, 3.1.......pi.....13 + 31 = 44...........440, a note piano........83 and 89....two 8s.........18281828, 3 - 10..............31 and 13 again...two 8s, e, and 880 hz, a second, another a note, an octave higher than 440 hz a sec..

79 + 83 = 162, 261 hz a sec backwards, mid c.......83 + 89 = 172, 1st 3 of e, backwards......1 up 2 down, a critical line pattern, 89 + 97 = 186, 000, e = mc ^2....speed of light, and 83 + 97 = 180, pi...bingo!!

Draw a line down from 83 to 89, cut in half, two triangles, right triangles from an equil triangle, i solved it!!
