The answer above is correct, but I do want to elaborate on how to receive this answer;
This pattern takes an alternate of positive and negative numbers at a time. If you can see for each positive number, there is a negative consecutively. Imagine these values were all positive. What would then be the difference between each? 3 * 3 = 9, 9 * 3 = 27, 27 * 3 = 81, and so each number would be 3 times the other. Now let us go back to the state we have at hand, negative and positive numbers. 81 * 3 = 243, and as we alternate between negative and positive numbers, 243 should be positive as the previous number - 81, is negative. We have now received our 5th term!
The questions asks us to determine the sum of each of the terms however, so let us do so;
Hope that helps as well!
Answer:
The opening price of the stock in the beginning of the day was $4.
Step-by-step explanation:
To be able to calculate the price of the stock at the beginning of the day, you have to consider that the equation to calculate the final price is equal to the opening price multiply for the result of one plus the increase or decrease percentage, which is:
final price=opening price*(1+0.04)
Now, you know that the final price is $4.16, so you can replace this value in the formula and solve for the opening price:
4.16=opening price*1.04
opening price=4.16/1.04
opening price=4
According to this, the answer is that the opening price of the stock in the beginning of the day was $4.

Answer:
The exponential growth model is given by this general expression:
And the exponential model decay model is given by:
Where a the initial amount r the growth factor of rate anf t the time.
The reason with we need to add 1+r in the base of the model is because each period of time 
we have an increase of the initial amount by a factor of (1+r) so after n periods we will have (1+r)^n times the initial amount.
Step-by-step explanation:
In general an exponential model is given by this formula:
Where:
a = the constant, b = the base and x x the exponent.
