Slope of line passing through two points (x1,y1 ) and (x2 ,y2 ) is given by
m= y2-y1/x2 −x1
Since the line passes through (−2,5) and (6,4)
We have
Slope(m)= 4-5/6−(−2) =− 1/8
A boy sells goods for 3/4 of a dollar. If at the end of the day, he made $12, how many goods did he sell?
Third term = t3 = ar^2 = 444 eq. (1)
Seventh term = t7 = ar^6 = 7104 eq. (2)
By solving (1) and (2) we get,
ar^2 = 444
=> a = 444 / r^2 eq. (3)
And ar^6 = 7104
(444/r^2)r^6 = 7104
444 r^4 = 7104
r^4 = 7104/444
= 16
r2 = 4
r = 2
Substitute r value in (3)
a = 444 / r^2
= 444 / 2^2
= 444 / 4
= 111
Therefore a = 111 and r = 2
Therefore t6 = ar^5
= 111(2)^5
= 111(32)
= 3552.
<span>Therefore the 6th term in the geometric series is 3552.</span>
