The sum of two consecutive even integers is 234. What is the larger integer?
leonid [27]
If the sum of two consecutive even integers is 234, the larger integer would be 118, and the smaller integer would be 116. This is because you take 234 and divide by 2. Take those numbers and add one to one side, and take away one number on the other side.

The first digit of a string of 2002 digits is a 1. Any two-digit number formed by consecutive digits within this string is divis
Umnica [9.8K]

The largest possible last digit in the string of 2002 digits and number divisible by 19 or 31 is 9.

Given the first digit of a string of 2002 digits is 1 and the two digit number formed by consecutive digits within the string is divisible by 19 or 31.

We have to tell the last largest digit of such number.

Two digit numbers divisible by 19=19,38,57,76,95.

Two digit numbers divisible by 31=31,62,93,124

Number started with 1 =19

Last digit is 9

We have said that the number should be divisible by 19 or 31 not from both and started with 1.

Hence the largest possible last digit and number divisible by 19 or 31 in this string is 9.
