One number is eight more than twice another if their difference is 25. The larger number is 42

It seems that each number is alternately one less and one more than twice the previous number.
The two numbers are 10 and 14.
9+4x=2x-1 2x=-10 x=-5
Because the number is decreasing in size (i.e. less than one) which means you are making it smaller. Try dividing a big number with any fraction. You'll see that it decreases. This is because a fraction is smaller than one and so it will decrease. Another way of looking at it is if you multiply a number by 1, you get the same number. Multiply by 2 and you get twice the number. Therefore, multiplying a number by less than one and your bound to get a smaller number.
