No it is not. It increases by 1 more each time.

So it is an increase of 5, then an increase of 6, then an increase of 7. This means it is not arithmetic.

Answer:

Step-by-step explanation:

h(x) - j(x) => $x^2-(2x^2-5)$

The negative sign out in front of the set of parenthesis changes the signs of everything inside the parenthesis, so now we have, without parenthesis:

$x^2-2x^2+5$ which simplifies down to

$-x^2+5$
