a) Explain why this sequence is an arithmetic sequence.
It is an arithmetic progression since it is a succession of numbers such that the difference of any pair of successive terms in the sequence is constant, in this case, it is 3.
b) Write out the sequence using blanks where appropriate.
Week|Distance
1 5
2 8
3 1 1
4 14
. .
. .
. .
c) Write the explicit formula for the sequence.
an = a1 + d*(n -1)
an = 5 + 3*(n - 1)
an = 5 + 3*n - 3
an = 3*n + 2
d) How far will the patient walk during the 12th week?
a12 = 3*12 + 2
a12 = 38
that is to say, in that week I walk 38 km
<em>q(x)=8x-7</em> is your equation.
When x = 4
Plug in 4 for x
q(4) = 8(4) - 7
Follow PEMDAS. Multiply 8 with 4
q(4) = 32 - 7
Subtract
q(4) = 25
(D) 25 is your answer
hope this helps
