Answer:
x = 32
Step-by-step explanation:
(2x + 60) + (3x - 40) = 180 because they are supplementary angles
5x + 20 = 180
5x = 160
x = 32
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...
