What is the recursive formula for -7,-1,5,11

1 answer:

3 0

-1 - (-7) = 6
5 - (-1) = 6
11 - 5 = 6
The common difference is 6.
If you add 6 to a term, you get the next term.

$a_0 = -7$

$a_n = a_{n - 1} + 6$

If f(x)=20, what does x equal?

Snowcat [4.5K]

Answer:

Step-by-step explanation:

$X=20$ because f (20) would also be 20. Since we don't know the value behind 20, we would suppose x is the value. The original equation is now $f(x)=x$ . If we do $f(20)=x$ we would get that (since x is being substituted) $f(20)=20$ .
