<span>The numbers (not counting 69) are all perfect squares. They are 7 squared, (what should be, possibly) 8 squared, 9 squared, and 10 squared. The next three numbers in the sequence would then be 121, 144, and 169.</span>
Answer = 5.5
You just have to add all the numbers together to get the answer
If the functions are inverses, then f(g(x)) = x.
A.

The functions are inverses of each other.
B. The domain of f(x) = x≠3. The domain of g(x) is x≠0.
The domain of f(g(x)) is (-∞, 0) ∪ (0, ∞).
The domain of g(f(x)) is (-∞, 3) ∪ (3, ∞).
What do you need to solve for?
X=r-4/7-s
S=-r/x+4/x+7
R=-sx+7x+4
