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}

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

the answer is b
