Try this suggested solution, note, 'D' means the region bounded by the triangle according to the condition. It consists of 6 steps.
Answers are underlined with red colour.
The first term, a, is 2. The common ratio, r, is 4. Thus,
a_(n+1) = 2(4)^(n).
Check: What's the first term? Let n=1. Then we get 2(4)^1, or 8. Is that correct? No.
Try this instead:
a_(n) = a_0*4^(n-1). Is this correct? Seeking the first term (n=1), does this formula produce 2? 2*4^0 = 2*1 = 2. YES.
The desired explicit formula is a_(n) = a_0*4^(n-1), where n begins at 1.
Answer:
0.4 gallons
Step-by-step explanation:
Length of a bedroom= 20 feet
Breadth of a bedroom= 15 feet
Height of a bedroom= 8 feet
Area of walls of a bedroom= 2(l+b)×h
Area of walls of a bedroom=2(20+15)×8 
Area of walls of a bedroom= 2× 35×8 
Area of walls of a bedroom=560 
Amount of paint in 1 gallon = 400 
Number of gallons required= 
Number of gallons required= 1.4 gallons
Hence, 0.4 extra gallons required
All real solutions
Everything cancels out once you multiply the top equation by two.
0 = 0 which means all real answers.
I hoping you meant question 3. Good luck!
