Infinite because it keeps going
ANSWER
EXPLANATION
The given series is
5 + 10 + 15 + 20 + . . . + 5n + . . .
The first term of this series 5
The constant difference is:
d=10-5=5
The +... at the end of the series means it does continue to infinity.
The series is infinite
2^2-4+6 is your answer
1,8,27,64,125
Step-by-step explanation:
7
Admission cost = $15
Cost per ride = $3
Total amount spent = $36
We can obtain the number of rides thus :
Let number of rides = x
Admission cost + (cost per ride * number of rides) = total amount spent
15 + 3x = 36
3x = 36 - 15
3x = 21
x = 21 / 3
x = 7
Number of rides = 7
