Powers of 2
If each generation doubles in size how many are there at:
|
|
1st = 1 2nd = 2 3rd = 4 4th = 8 5th = 16 6th = 32 7th = 64 8th = 128 9th = 256 10th = 512 |
11th = 1,024 12th = 2,048 13th = 4,096 14th = 8,192 15th = 16,384 16th = 32,768 17th = 65,536 18th = 131,072 19th = 262,144 20th = 524,288 |
21st = 1,048,576 22nd = 2,097,152 23rd = 4,194,304 24th = 8,388,608 25th = 16,777,216 26th = 33,554,432 27th = 67,108,864 28th = 134,217,728 29th = 268,435,456 30th = 536,870,912 |
31th = 1,073,741,824
32th = 2,147,483,648 [about the world population in 1940]
and we are only half way through the chess board!
