It should be noted that demand is an economic principle that refers to a consumer's desire to purchase goods and willingness to pay a price.
<h3>
What is a demand?</h3>
Your information is incomplete. Therefore, an overview of demand will be given. It should be noted that what a buyer pays for a unit of the specific good or service is the price while the total number of units purchased at that price is the quantity demanded.
Based on the information given, you can use the demand formula, Qd = x + yP, to find a demand line where Qd represents the number of goods demanded, x represents the quantity and P represents the price.

I don't know exactly how to label these. I'll start from the left and go to the right. The formula for all of these questions is Sum = a(1 - r^n)/(1 - r)
Left
The complete series is 1 3 9 27 81 and just adding these as you see them, you get 1 + 3 + 9 + 27 + 81 = 121
Sample calculation
i = 1
3^(1 -1) = 1
i = 4
1 * 3^(4 - 1)=3^3 = 27 Just what the series says you should get.
Sum using formula
Sum = 1(1 - 3^5)/(1 - 3) = 1 * (1 - 243)/(1 - 3) = - 242/-2 = 121
Second from the left
Series: 3 6 12 24 48
Sum by hand = 93
Sample Calculation
i = 1
3*2^(1 - 1) = 1
i1 = 3
3 * 2^(3 - 1) = 3 * 2^2 = 3 * 4 = 12 which is what you should get.
Sum using formula
Sum = 3 (1 - 2^(5 - 1) / (1 - 2)
Sum = 3 (1 - 32) / - 1
Sum = 3(-31) / (- 1) = 93
Second from the right.
Series: 2 6 18 54
Sample Calculation
i = 1
t1 = 2* 3^(1 - 1) = 2*3^0 = 2*1 = 2
i = 4
t4 = 2 * 3^(4- 1)
t4 = 2 * 3^3
t4 = 2 * 27
t4 = 54 just as it should
Sum with formula
Sum = 2( 1 - 3^4) / ( 1 - 3)
Sum = 2(1 - 81)/ -2
Sum = 2( - 80) / - 2
Sum = 80
Entry on the right
Series: 1 2 4 8 16 32 64
Sum by hand: 1 + 2 + 4 + 8 + 16 + 32 + 64 = 127
Sample Calculation:
i = 1
2^(1 - 1) = 2^0
2 to the zero = 1
i = 6
t6 = 1( 2^6)
t6 = 1 * 2^6 = 64
Sum using the formula: 1*(1 - 2^7)/(1 - 2) = (1 - 128)/(-1 = 127
