the question does not present the options, but this
does not interfere with the resolution
Let
a1=-4
a2=-24
a3=-144
a4=-864
a5=?
we know that
a2/a1=-24/-4----> 6-------> a2=6*a1
a3/a2=-144/-24---> 6-----> a3=6*a2
a4/a3=-864/-144---> 6----> a4=6*a3
therefore
a5=6*a4-----> a5=6*(-864)------> a5=-5184
hence
the formula is
an=6*a(n-1)

Answer:
The answer would be 22/12 or 1 and 11/12
Step-by-step explanation:
1/2+2/3+3/4
First get common denominators so you have a denominator of 12 so 6/12+8/12+9/12
Add those together and you get 23/12 but you have to subtract one because that's what the problem says so you get 22/12
A cone that is sliced through the vertex would make the shape of a triangle.
You are told the h eight is 10 cm and the radius is 4 cm.
The radius would be half the base, so the base would be 4 * 2 =8 cm.
The area of the triangle is found by multiplying the base by the height, then dividing by two.
Area = 8 x 10 = 80
80 / 2 = 40 square centimeters.
