first term is given to us. A one is
2
00:00:03.439 --> 00:00:07.950 A:middle L:90%
one and the other terms. We use this formula
3
00:00:09.710 --> 00:00:12.460 A:middle L:90%
. So you two were doing that by using this
4
00:00:12.460 --> 00:00:16.559 A:middle L:90%
formula where in plus one is acting Isar eight to
5
00:00:16.690 --> 00:00:18.449 A:middle L:90%
, which means that our A N is acting,
6
00:00:18.449 --> 00:00:27.519 A:middle L:90%
as are a one. So five times one minus
7
00:00:27.519 --> 00:00:34.549 A:middle L:90%
three two a three is five times a to minus
8
00:00:34.600 --> 00:00:39.479 A:middle L:90%
three. So five times two minus three So ten
9
00:00:39.479 --> 00:00:47.670 A:middle L:90%
minus three seven a four, five times seven minus
10
00:00:47.679 --> 00:00:52.189 A:middle L:90%
three seven because that they're a three value. So
11
00:00:52.189 --> 00:00:58.909 A:middle L:90%
this is thirty five minus three So thirty two and
12
00:00:58.909 --> 00:01:07.769 A:middle L:90%
then a five is five times thirty two minus three
13
00:01:08.700 --> 00:01:11.590 A:middle L:90%
, which is one fifty seven.
