1 and 2 will go into the given three numbers evenly with no remainders
factors of 8 - 1, 2, 4, 8 factors of 20 - 1, 2, 4, 5, 10, 20 factors of 22 - 1, 2 ,11, 22
8 + 38 + 20 = 66/3 = 22
22 + 8 - 10 = 20 Therefore, the number he is thinking of is 22.
22 (2+2=4x2=8+2=10x2=20+2=22
The next number in the series 1 2 4 8 10 20 22 is
20 + (9 - 8)*2 = 22.
factors of 8 - 1, 2, 4, 8 factors of 20 - 1, 2, 4, 5, 10, 20 factors of 22 - 1, 2 ,11, 22
5=22+12 8=22+22 13=22+32 20=22+42 29=22+52 40=22+62
8 + 38 + 20 = 66/3 = 22
The difference between 72 and 16
20
What goes into 22 and 100 evenly
2.5
1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440.
(22/4)x8-20=24
22 + 8 - 10 = 20 Therefore, the number he is thinking of is 22.
