Answer:
Step-by-step explanation:
r = 21/42 = 1/2 ( also 10.5 / 21 = 1/2)
This is a Geometric Sequence with first term 42 and common ratio 1/2.
There may be more than one solution, but if we take the difference between the numbers of the sequence, we get
3-1, 11-3, 43-11
=2,8,32
which are powers of 2
=2^1, 2^3,2^5
If we believe the next difference is 2^7=128, then the next in the sequence will be 43+128=171
Shade in 4 of the squares.
Answer:
B
Step-by-step explanation:
I can't really see the problem, however I believe B is the only one that shows an infinite number of solutions.
10 inches squared. Area is length times width. 15/2 x 4/3 = 60/6 = 10^2.
