Answer:
20
Step-by-step explanation:
f(x) = 30
30 = 1.8x -5.4
35.4 = 1.8x
x = 35.4/1.8
x = 19.666
The explicit formula would be

.
This is a geometric sequence, since we are multiplying each term by a constant to find the next term.
The explicit formula for a geometric sequence is given by

,
where g₁ is the first term and r is the common ratio, or the number that is multiplied to get the next term.
Our first term is 5, and the common ratio is 3.
1. The total of x and 29.
This is because we see addition going on, so x+29 is the total of something
Hope this helps :)
