Answer:
a=5
d=2
then t18=?
now we khow that
t18=a+(n-1)d
= 5+(18-1)2
= 5+17×2
=5+34
=39ans
the answer I got is 8...........
Distribute the 2 through the parentheses
on the right side of the equation.
2(y) is 2y and 2(2) is 4.
So the problem now reads 6 = 2y + 4.
Now we can subtract 4 from both
sides of the equation to get 2 = 2y.
Now divide both sides of the
equation by 2 and <em>1 = y</em>.
