Birdwatching Every Day!Discrete Mathematics Level 1
Every day, for the next one year, he will visit one location around the globe.
On the first day, he sees 1 bird. This number of birds he sees increases by one every day, so the number that he sees is the same as the day of the year. For example, on the 29th day, he saw 29 birds.
How many birds would he have seen by the end of the year?
