40 5 10 20 40 80 160.......double the number each time.
20 Each time it divides by 2... 160/2=80; 80/2=40; 40/2=20
The next number in the sequence 5, 10, 20, 40 is 80. Each number in the sequence is multiplied by 2 to get the next number. So, 40 multiplied by 2 equals 80.
10-20 16 20-30 4 30-40 _ 40-50 _ 50-60 _ 60-70 2
2, 4, 5, 8, 10, 20
25 100 80
These may help you answer your questions: 1, 2, 4, 5, 8, 10, 20 and 40.
40 5 10 20 40 80 160.......double the number each time.
20 Each time it divides by 2... 160/2=80; 80/2=40; 40/2=20
Each number is multiplied by negative 2 to get the next number. 5 x -2 = -10 -10 x -2 = 20 20 x -2 = -40 -40x -2 = 80 So the next logical number in the series 5 10 20 -40 would be 80.
Because 10 is a factor of 20 and 40. So any number which divides 10 evenly divides the factor of 20 or 40 evenly
The next number in the sequence 5, 10, 20, 40 is 80. Each number in the sequence is multiplied by 2 to get the next number. So, 40 multiplied by 2 equals 80.
The LCM of 8, 10, and 20 is 40. Multiples of 8: 8, 16, 24, 32, 40, 48...... Multiples of 10: 10, 20, 30, 40, 50, 60...... Multiples of 20: 20, 40, 60, 80 The smallest number that all three numbers go into evenly is 40. Therefore the LCM of 8, 10, and 20 is 40.
When it is a multiple of 10, such as 20, 30, 40, etc.
|-20 - (-40)| = 20 |-20 - 10| = 30 -20 is closer to -40 than 10.
