Which sequence below represents an exponential sequence? A) {2, 6, 10, 14, 18,...} B) {3, 5, 9, 16, 24,...} C) {4, 8, 24, 96,...

Answer:d
Step-by-step explanation:
Clearly from observation option D is the exponential sequence
256,64,16,4 is decreasing exponential function
for other option they simply follow an AP
2,6,10,14,18
common difference d=4
There are three different possibilities.
Ice cream + x
Ice cream + x
Ice cream + x
x = toppings
Round pan volume is:
3.14•r^2•h
D=7 so r=3.5 in
3.14• (3.5^2)•2 = 76.97 in^3
Rec. pan vol. is :
9•6•2= 108 in^3
Rec. Pan is larger because 108 in^3 is > 76.97 in^3 :) .
The icing that will be needed to frost the round cake pan is:
We need to find the surface area:
S.A= 3.14r^2 + 2 • 3.14•r • h .... 3.14 is the value of PI
So, S.A= 3.14• 3.5^2 + 6.28• 3.5• 2= 82.47 in^2 the icing that'll be needed to frost the round cake pan.
Icing that will be needed for the rec. cake pan is:
2•9•2=36 in^2
6•9•2= 108in^2
6•2= 12 in^2
S.A= 156 in^2 the icing needed to frost the rec. cake pan .... the S.A of all sides except the bottom one :).
Good luck ;-)
Answer:
see explanation
Step-by-step explanation:
The geometric mean of 2 numbers a and b is 
The third term is the geometric mean of the first and fifth terms, that is
a₃ = 
= 31.5
The second term is the geometric mean of the first and third terms, that is
a₂ = 
= 10.5
The fourth term is the geometric mean of the third and fifth terms, that is
a₄ = 
= 94.5
Thus the sequence is
3.5, 10.5, 31.5, 94.5, 283.5
