The numbers 1 to 72 add up to (1+72) x 72/2 = 73 x 36 = 2628
If we take away what Josh got we have 2628 - 2521 = 107
Pages in a book are odd on the first side and even on the second, so pages 11 and 12 are on the same sheet.
107 / 2 = 53.5 so the missing page had 53 on one side and 54 on the other side.
The remaining pages would have been numbered 1, 2, 3, ..., 51, 52, 55, 56, ... 71, 72

An inequality has g=1 as a solution, but g=2 is not a solution . What is the inequality?
timama [110]
We know 1 is a solution, but 2 is not.
We also know that 1 is 'less than' 2
Key words: less than
That means are inequality will be: g<2
Now if we plug 2 in for g it will say:2<2 
We know two is not less than two, two is equal to two.
Now let's plug 1 in for g: 1<2
So we know 1 is less than 2. Therefore, this inequality is true.
Hope that helped :)
