Answer: 174
Step-by-step explanation:
For this problem, let's divide the number by two since we know it's a combination of two numbers in a series as they are two consecutive book pages.
349 / 2 = 174.5
Note, that the number we have is a decimal, and page numbers cannot be partial numbers, they must be integers. With this, we can take the lower and the upper of our decimal numbers to retrieve the two-page numbers.
174.5 (Upper) ==> 175
174.5 (Lower) ==> 174
With this, we can verify these numbers have a sum of 349.
175 + 174 =? 349
349 == 349
So indeed, these numbers are a sum of 349. Now that we know these are our page numbers, we know 174 will come before 175 since page numbers are sequential.
Cheers.
