# Lynn counts numbers from 105 and adds 4 each time. So she counts 105, 109, 113, and continues. What is the largest three-digit whole number that Lynn counts?

The answer is **997** since the distance is 4 and the first sequence is 105.

105 + 988 = 1093 - It's already 4 - digit number.

105 + 904 = 1009 - still a 4 - digit number.

105 + 892 = 997 - it's a 3-digit number. Just simply add 3 to it and it will become 4 - digit, so that, it's the largest three-digit number in the sequence.
