Okay, here we have a formula, am is equal to 100 times 2 to the pound m minus 1.
00:08
This gives us a number of bacteria in six hour periods.
00:15
Okay, we're asked to find a total number of bacteria in 24 hours.
00:20
Okay, so hopefully you can see that this is four six hour periods.
00:25
So we need the first four terms of this sequence.
00:29
So we need a 1, a 2, a 3, and a 4.
00:33
The first one is 6 hours.
00:35
The next one is really 12 hours.
00:38
The next one is 18 hours.
00:40
And the last one is those 18 to 24 hours.
00:44
So we're going to get these four terms and then add them up...
