Answer:
<em>5,9,13,17,21</em>
Step-by-step explanation:
We can the values in "n"
a(1)=4(1)+1
a(1)=5
a(2)=4(2)+1
a(2)=9
a(3)=4(3)+1
a(3)=13
a(4)=4(4)+1
a(4)=17
a(5)=4(5)+1
a(5)=21
As you can see, each value consecutively increases by 4, this is also known as the common difference (d).

Answer:
67.307
Step-by-step explanation:
30×25=750
100×80=8000
750+8000=8750
8750/130=67.307... total hits divided by total games
Answer: Kate = 40/3 Her father = 50
Step-by-step explanation:
Let Kate's age in the present be K
And Kate's father's age in the present be F
3(K+5) = F+5
6(K-6) = F-6
Rearrange the first equation to get
3K+15 = F+5
3K+10 = F
Substitute that into the second question
6K-36 = 3K+10-6
3K = 40
K = 40/3
So F = 3*40/3+10 = 50
225/5 = 45
This means the parents gave her five dollars forty five times. If they gave her a five every time she saved one dollar, you just have to multiply the money she saved each time and the number of times she saved it, and you'll get the answer.
Wendy saved $45 by herself
