Answer:
Answer is {–4, 0, 4}
Step-by-step explanation:
Given parameters:
Distance covered = 925 miles
Quantity of gas used = 37 gallons
Cost of gas per gallon = $5.909
Unknown:
Amount spend on gas = ?
The amount spent on gas would:
Cost of gas = cost of gas per gallon x quantity of gas used
Input the parameters and solve;
Cost of gas = $5.909 / gallon x 37 gallons = $218.6

Answer:
64 cupcakes
Step-by-step explanation:
Tray 1 = 2 cupcakes
Tray 2 = 4 cupcakes
Tray 3 = 8 cupcakes
Tray 4 = 16 cupcakes
Tray 5 = 32 cupcakes
Tray 6 = ?
This is a geometric progression
First term, a = 2
Common ratio, r = 4/2
= 2
6th term = ar^n-1
= 2 × 2^6-1
= 2 × 2^5
= 2 × 32
= 64
The 6th tray will have 64 cupcakes
