A night watchman wrote a sequence of numbers to pass the time. He started with a certain natural number. Each subsequent term in the sequence was formed by adding a specific number to the previous term: to the first term he added 1, to the second 3, to the third 5, to the fourth 1, to the fifth 3, to the sixth 5, to the seventh 1, and so on. It is known that the sequence contains the numbers 40 and 874.

1. Which number follows immediately after 40 in the sequence, and which follows immediately after 874?
2. In the sequence, there are two consecutive terms whose sum is 491. What are these two numbers?
