Answer:
20
Step-by-step explanation:
Evaluate for y= −5
(−5)2+(2)(−5)+5
(−5)2+(2)(−5)+5
=20
The formula for arithmetic sequence is given by:
an=a+(n-1)d
where:
an=nth term
a=first term
n=number of terms
thus our first term will be:
a1=8
a2=8+(2-1)(-6)=2
a3=8+(3-1)(-6)=-4
a4=8+(4-1)(-6)=-10
a5=8+(5-1)(-6)=-16
a5=-16
thus the sequence will be:
8,2,-4,-10,-16...

<span>2divided 5 =</span>0.4
if 2 is over the 5 you divide the 2 by 5 to get the decimal and then you get 0.4/
Solve. -6 = 14 - z/3Subtract 14 from both sides
-20 = -z/3
Multiply -3 by both sides to get rid of the negative and 3 with the z.
z= 60
