Write an equation for the nth term of the arithmetic sequence. Then find a10. −3,−6,−9,−12,...

an=

a10=

-3n

a10= -30

Step-by-step explanation:

the distance between -3 and -6 is 3.

if you multiply 3 by the 1st term, it's just 3, so the 3 needs to be a -3.

For a10, you plug in 10 into the equation which is -3n. and that is -30.

step-by-step explanation:

sry but any answer choices

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
