Write a recursive expression
When n = 1
When n = 2
can be rewritten as
Substitute 3 for f(1)
Express 1 as 2 - 1
----- (1)
When n = 3
can be rewritten as
Substitute 8 for f(2)
Express 2 as 3 - 1
------ (2)
Write out (1) and (2)
Replace 2 and 3 with n in both cases; This gives
Hence;
The recursive is
Answer:
smallest amount of sugar = 40 kg
largest amount of sugar = 80 kg
Step-by-step explanation:
2 : 3 : 4
2 + 3 + 4 = 9
180 ÷ 9 = 20
Therefore,
2 : 3 : 4 = (2 x 20) : (3 x 20) : (4 x 20) = 40 : 60 : 80
So the smallest amount of sugar = 40 kg
and the largest amount of sugar = 80 kg
Right answer is 1.4013841
