Another geometric sequence we're trying to prove.
00:04
So this one starts with three, then goes to three over two.
00:09
That's really bad three.
00:10
Three over two, three over four, three over eight.
00:18
And again, is this a geometric sequence? and if so, what is r? first thing i want to do is i want to put this over one.
00:30
Because the rest of them are fractions.
00:31
It just makes me happy.
00:32
Now, when i look at this, i notice that this is either plus 1 or times 2.
00:39
Here is either plus 2 or times 2, and this is either plus 4 or again times 2.
00:48
The only one that is the same across the board would be our times 2s...
