Answer:
4 14/15
Step-by-step explanation:
8 3/5 - 11/3
8 9/15 - 55/15
8 9/15 - 3 10/15
7 24/15 - 3 10/15
4 14/15
The absolute value of an given number is always positive. So, when adding two to any positive number will always be greater than the number by itself.
a geometric sequence is a bunch of numbers where you can get from a number to the next number by multiplying the previous number by a certain number
might be confusing so here's an example
1,2,4,8,16
each term is multiplied by 2 to get next term, that number that each term is multiplied by is called the common ratio
formula for geometric sequence is
![a_n=a_1(r)^{n-1}](https://tex.z-dn.net/?f=a_n%3Da_1%28r%29%5E%7Bn-1%7D)
where
is nth term
is first term
r is teh common ratio
n=which term
in our example
1,3, 9, 27, 81
each term is being multiplied by 3 so it is a geometric sequence and thus r=3
also first term is 1 so ![a_1=1](https://tex.z-dn.net/?f=a_1%3D1)
so the formula is
or in function notation ![f(n)=1(3)^{n-1}](https://tex.z-dn.net/?f=f%28n%29%3D1%283%29%5E%7Bn-1%7D)
