Answer:
Either 1 or 0
Step-by-step explanation:
The average would be the total amount divided by the 2 groups, so the answer would be 37.5 years old.
Using decimal multipliers, it is found that a rate of return of 5.2% in the third year will produce a cumulative gain of 16%.
The <u>decimal multiplier</u> for a increase of a% is given by:

In this problem, two increases of 5%, thus:

Another of x, that we want to find, and the result is a increase of 16%, thus:

The three increases(5%, 5% and x%) result in a increase of 16%, thus:



1.052 - 1 = 0.052
A rate of return of 5.2% in the third year will produce a cumulative gain of 16%.

Consecutive numbers are always 1 away from each other
3,4
so consecutive is represented by
x and x+1
so sum is -171
x+x+1=-171
add like terms
2x+1=-171
subtract 1 from both sides
2x=-172
divide both sides by 2
x=-86
subustitute
x+1=otehr number
x+1=-86+1=-85
answer is -85 and -86
