Find the common ratio r for each geometric sequence and use r to find the next three terms. 8, 4, 2, 1, ... 200, -80, 32, -12.8, ...

the sequence is the a geometric sequence because the terms has a common ratio. the common ratio = -80 / 200 = -2 / 5common ratio = 32 / -80 = -2 /5

so the next to term can be solve multiplying the last term with the common ratio

x = -12.8 ( -2 / 5)x = 5.12

y = 5.12 ( - 2 / 5)y = -2.048

Step-by-step explanation: HOPE THIS HELPS!!

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
