00:02
That first term is supposed to be one half.
00:09
Okay, one thing that we notice is that there's in the denominator, all the values in the denominator are always just increasing by one.
00:20
So they're always going to be increasing by one.
00:25
And we need to add one here so that we start on two, because it should start on two.
00:32
Okay, so if we have n plus one in the denominator, that means that we'll start on two, but it will be one more every time.
00:39
This n is going to make us be one more in the previous term every time in the denominator.
00:48
And we're also going to be alternating signs.
00:51
First term is positive, next term is negative, next term is positive.
00:56
So we're alternating signs.
00:58
So maybe something like this...
