Examine the given terms of the sequence. Is every term the same multiple of the previous term? If so, that multiplier is called the "common ratio," r
If "a" is the first term of the sequence, then a_n = (a)(r)^(n-1).
Answer:
The answer is 7
Step-by-step explanation:

Answer:
D) 2/3
Step-by-step explanation:
Constant of proportionality formula:
k = y/x
8/12 = 2/3
10/15 = 2/3
12/18 = 2/3
14/21 = 2/3
Answer:
b
Step-by-step explanation:
sin θ=√(1-cos²θ)=√(1-9/25)=√(16/25)=4/5
sin 2θ=2sin θ × cos θ=2×3/5×4/5=24/25
