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

term plus for or simplified one fourth acts Plus it

plus four for one eight seven So our ratio is

one eighth x plus seven all over acts well change
