In a geometric progression:
a, b, c, d...
The common ratio can be obtained using:
b/a = c/b = d/c
b/a = 112 / 64 = 1.75
c/b = 196 / 112 = 1.75
d/c = 343 / 196 = 1.75
The common ratio = 1.75
Answer:
D.
Step-by-step explanation:
That is the answer. The complex numbers have opposite real parts.
The rate of change is 4 so your answer would be D. 4
5×2+8-4+1=15
cause
5×2=10
10+8=18
18-4=14
14+1=15
