.........15..........24.........35.........48.........63
...............9..............11..........13..........15.........
.......................+2.........+2.........+2.............

Berarti untuk urutan selanjutnya
U6 = 63+17 = 80
U7 = 80+19 = 99
U8 = 99 + 21 = 120
U9 = 120 + 23 = 143
U10 = 143 + 25 = 168
U11 = 168 + 27 = 195
U12 = 195 + 29 = 224
U13 = 224 + 31 = 255
U14 = 255 + 33 = 288
