The human relationship formula betwixt U_n together with S_n :

Information :
S = Geometry series
r = Ratio
a = The offset tribe
U = Tribe
n = Tribal position

Please induce upwards one's heed the total of 1 + ii + iv + 8 + ... (up to thirteen tribes) !

Answer:
a = 1
r = 2/1 = 2
n = 13

thus the total of 1 + ii + iv + 8 + ... (up to 13 tribes) is 8191.
