Other possible details include startup funds (e.g. US$1M over 10 years), lab space (dry/wet lab, exclusive use square footage), and access to shared facilities (big experimental equipment). Lab space and shared facilities aren't free, so the cost is often deducted from your startup funds.
The first few abundant numbers are 12, 18, 20, 24, 30, 36, 40, 42, 48, ... Note that most of these appear to be even; the first odd one does not appear until 945. This is quite remarkable, as it provides a naturally occurring example of a large number. After 945, the odd-abundant numbers are 1,575, 2,205, 2,835, 3,465, ...
The 16 is the sum of the first and last terms, a 1 + a n. The 2 is because we added the sum twice and will remain a 2. Therefore, the sum of the first n terms of an arithmetic sequence is S n =n/2*(a 1 +a n). There is another formula that is sometimes used for the n th partial sum of an arithmetic sequence.
