answer sheet is wrong
Sam - 100, 200, 300, 400
Alan - 200, 190, 180, 170

u might also want to write to the publisher and ask them

Thanks a lot...

Find the missing number
16 - 8 - 12 - 6 - 10 - ? - 9

Is the answer 5?

divide by 2, then add 4.

16/2 = 8
8+4 = 12
12/2 = 6
6 + 4 = 10
10/2 =5
5 + 4 = 9
