Input + 2n + 1 = Output

Sorry again but what does 2n mean. Thank you.

math  Ms. Sue, Tuesday, July 31, 2012 at 5:01pm
2n = 2 times n
(2 * 2) + 1 = 5
(4 * 2) + 1 = 9
(10 * 2) + 1 = 21

math  Damon, Tuesday, July 31, 2012 at 5:06pm
output = 2 n + 1
if n = 2,
output = 2*2 + 1 = 5
if n = 10
output = 2*10 + 1 = 21
