How do I solve for the missing numbers

going from left to right: 200, 400, 800

Step-by-step explanation:

25 x 2 = 50

50 x 2 = 100

100 x 2 = 200

200 x 2 = 400

400 x 2 = 800

just follow the pattern

{800, 400, 200, 100, 50, 25}

Step-by-step explanation:

Look at the last three numbers.  Notice that each is half of the previous number:  50 is half of 100, etc.

Thus, the number preceding 100 must be 200; the one before that is 400, and the first number is 800.

Thus the sequence is {800, 400, 200, 100, 50, 25}
