Do you have the whole question? The problem that you gave does not have a problem....
f(x)=2x+5
first find inverse
write it without f(x)
y = 2x + 5
x = 2y + 5 swap the variables, now solve for y
- 5 -5
x - 5 = 2y
/2 /2 divide both sides by 2
(x-5)/2 = y
so f-1(x) = (x-5)/2
f-1(8) = (8-5)/2
= (3)/2
f-1(8) = 3/2
Answer:
Next term is 7. Sequence generator is 3.
