Answer:
1) 36
b) 5
c) 3.0
Step-by-step explanation:
1) The recursive formula that defines the given sequence is
That means we keep adding 4 to the subsequent terms:
The sequence will be:
12,16,20,24,28,32,36,...
Therefore the seventh term is 36.
2) The sequence is recursively defined by;
This means, we have to keep subtracting 5 from the subsequent terms.
The sequence will be;
20,15,10,5,...
Therefore the fourth term is 5
3) The sequence is recursively defined by:
f(n+1)=f(n)+0.5
where f(1)=-1.5
This means that, the subsequent terms can be found by adding 0.5 to the previous terms.
The sequence will be:
-1.5,-1.0,-0.5,0,0.5,1,1.5,2.0,2.5,3.0,....
Therefore f(10)=3.0
Answer:
Step-by-step explanation:
Given: A tourist first walked 17km with a speed of v km/h.
Since
therefore,
Let be the time he walked with speed v.
then
Also he hiked 12 km uphill with the speed that was 2 km/hour less than his original speed.
Let be the time he hiked 12 km,
Then
The total time for the whole trip is given by:-
Substitute the values of and
in the equation, we get
