Fractions they are easy REALLY!!
Answer:
a_n = 2^n + 3
Step-by-step explanation:
The first differences have a geometric progression, so the explicit definition will be an exponential function. (It cannot be modeled by a linear or quadratic function.) The above answer is the only choice that is an exponential function.

First differences are ...
(7-5=)2, 4, 8, 16
I got the answer to be 42.
Answer:
27
Step-by-step explanation:
If you have an exponent that is a fraction, you need to make a radical with the index from the denominator and an exponent of the radicand from the numerator.
(243)^3/5=(![\sqrt[5]{243}^3](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B243%7D%5E3)
)
This would come out as ![\sqrt[5]{14348907^}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B14348907%5E%7D)
. this further simplifies down to the final answer of 27
