The Nomarchs were the provincial governors nome = province, archos = rule). They ruled them on behalf of the Pharaoh. The Pharaoh and his council oversaw their activity.
A governor of a province. For example Ancient Egypt had 42 nomarchs for all their provinces, which are called nomes. That's why governors are called nomarchs.
42 is between 41 and 43.
Half way between 36 and 42 is (36 + 42) ÷ 2 = 39.
Halfway between 42 and 82 is (42 + 82) ÷ 2 = 124 ÷ 2 = 62.
58 = 100 - 42
42 - 5.75 = 36.25
There seems to be a statistical correlation, see http://pn.psychiatryonline.org/cgi/content/full/42/6/20-b
There are 17 odd numbers between 42 and 76. (76 − 42) ÷ 2 = 17
86 - 42 = 44
(14 + 42) / 2 = 28
range = 58 - 42 = 16
The number midway between two numbers is the average of those two numbers. In this case, the average of 42 and 18 is (42 + 18) / 2 = 60 / 2 = 30. Therefore, the number midway between 42 and 18 is 30.
