Question 161771
here we go with the letter thing...


if x is the number on the 1st page, then the number on the 2nd page is x+1


the product is x^2+x __ this equals 812 __ x^2+x=812


you are looking for two factors of 812 that are one number different
__ the square root of 812 (on a calculator) is 28.5 (approx)


so 28 and 29 are good bets
