40 5 10 20 40 80 160.......double the number each time.
1 x 5 = 5 5 x 10 = 50 ; 10 is 5+5 50 x 20 = 1000; 20 is 10+10 1000 x 40 = 40,000 ; 40 is 20 + 20 40,000 x 80 = 3,200,000; 80 is 40+40 therefore the next 2 numbers are 40,000 and 3,200,000
If you mean: 5, 10, 20, 40 then the following number is twice the previous number which will be 80
10
40/10 = 20/a 4= 20/a 20/4 = a a= 5
40.
80
40 5 10 20 40 80 160.......double the number each time.
If you mean: 5 10 20 40 then it is 80
Double it every time and so the next number will be 80
1 x 5 = 5 5 x 10 = 50 ; 10 is 5+5 50 x 20 = 1000; 20 is 10+10 1000 x 40 = 40,000 ; 40 is 20 + 20 40,000 x 80 = 3,200,000; 80 is 40+40 therefore the next 2 numbers are 40,000 and 3,200,000
1, 10, 2, 20, 3, 30, 4, 40, 5, 50, and so on.
These may help you answer your questions: 1, 2, 4, 5, 8, 10, 20 and 40.
|-20 - (-40)| = 20 |-20 - 10| = 30 -20 is closer to -40 than 10.
40 is the outlier of10 15 10 20 10 20 40
160 220 290
If you mean: 5, 10, 20, 40 then the following number is twice the previous number which will be 80
