Answer:
f(n) = 2 * f(n - 1) + 1
Step-by-step explanation:
First, notice that the difference between each neighboring term is different, so it is not linear, so we can rule out A and B. Now, it's all about finding a pattern. Eventually, through guess and check, you will get 2 * f(n - 1) + 1.
Perhaps there was a typo in C? Idk!!
Answer:
an = 2 + n
Step-by-step explanation:
The differences between terms are all 1. The first term is 3. The general form of the general term is ...
an = a1 + d(n -1)
Filling in a1 = 3 and d = 1, we have ...
an = 3 + n - 1
an = 2 + n . . . . . . simplify
If you were to round it, a possible answer could be 9,997
Answer:

divide each term by two and simplify.
Give me my milf.
Consecutive integers = in this situation double-digit whole numbers
So as there are 3 of them let's say 2 are 11 because that would be the highest consecutive number so 11+11= 22 and 48-22=26 so the three have the ages of 11,11,26 and the oldest would be 26 ;)
