Common difference is +6 and I think nth term is 5 (pretty sure it's always the first term) and the second one im not so sure about I'm sorry.
People are kinda rude sometimes
Answer:
C: <u>19</u>
Step-by-step explanation:
To start we would resolve the absolute value of
. We know that absolute value is the distance from zero so it would be 3.
Our new equation is 
Now we need to solve in the order of PEDMAS starting with parenthesis to get 
Next in PEDMAS we have Division/Multiplication since we don't have any exponents. We do all the division and multiplication left to right so we would divide to get
and then multiply to get
.
Finally, we only have addition left over so our answer would be 
-1,-2,-4
an = a1 * r^(n - 1)
a1 = first term = -1
r = common ratio = 2
so the equation would be : an = -1 * 2^(n - 1)
