15%

Step-by-step explanation:

First add together the percentages that have been shown to you. It should look like this:

35+25+15+10=85

Know that every pie chart must add up tp 100%, and this is only 85%. We should subtract the 85% we have from 100%. It should look like this:

100-85=15

Therefore, 15% is your answer.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
