Thank you We sneak and here's your smoke usually brought

00:05

to you by decreasing terms No that would be decreasing

00:11

All right After the first term acts each term is

00:14

determined as half of the previous term plus four What

00:19

is the ratio of the fourth term The first heart

00:23

in a hair The potential answers You'll see this a

00:26

lot okay through this question were asked to find the

00:30

ratio of the fourth term to the first well ratio

00:35

is just a relationship between two numbers So to find

00:40

the ratio between the fourth term and the first way

00:43

no we should take the value of the fourth term

00:46

and divide it by the value The first term which

00:48

is given to us his act Right now all we

00:51

have to do is find the value of the fourth

00:53

term Well we're told after the first term acts each

00:56

term is determined as half of the previous term plus

01:00

four so the second term will be half of the

01:03

first term plus four or one half x plus four

01:08

got it Third term will be half of the second

01:11

term plus for or simplified one fourth acts Plus it

01:16

and the fourth term will be half the third term

01:18

plus four for one eight seven So our ratio is

01:24

one eighth x plus seven all over acts well change

01:28

the fraction one eighth into decimal form which is zero

01:33

point one two five and a correct answer is c

01:36

point one to five acts plus seven all over axe 00:01:41.219 --> [endTime] Yeah
