1,2,4,16,32,64 missing number

The pattern is of ×2

So the missing number will be

1,2,4, 8 ,16,32,64

8

Step-by-step explanation:

Just do a sum like 1+1 equals 2, then 2+2 equals 4, 4+4 equals 8, 8+8 equals 16, I hope you understand :)

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
