Answer:
- geometric
- arithmetic
- neither (Fibonacci sequence)
Step-by-step explanation:
If ratios are the same, it is geometric:
8/4 = 16/8 = ... = 2
If differences are the same, it is arithmetic:
-4-(-8) = 0 -(-4) = ... = 4
If neither is the case, it is neither:
3-2 ≠ 5 -3
3/2 ≠ 5/3
In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)
Answer:
48
Step-by-step explanation:
by dividing 9 by 6 you get 1.5 and by using distribution you also multiply 32 by 1.5 to get 48
Answer: width = 42, length = 74
Step-by-step explanation: 42 + 32 = 74
42 + 42 + 74 + 74 = 232
Opposite sides are parallel
Step-by-step explanation:
= 5 • ( 4• x )
= 5 ( 4x )
= 20x
