Step-by-step explanation:
Answer:564
Step-by-step explanation:
18.8*20=564
Answer:
B
Step-by-step explanation:
We can get two equations from the inequality:

We just need to simplify both equations to get our answers:


The two answers we get are:

Which is also B.
Geometric progresión:
we can calculate any term, using this rule:
an=a₁*r^(n-1)
a₁=the first term
r=the common ratio
a₆=128
r=2
an=a₁ * r^(n-1)
128=a₁ * 2⁶⁻¹
128=a₁ * 2⁵
128=a₁ * 32
a₁=128/32=4
Solution: a₁=4
