If the population quadruples every period say hour, that means the "rate of growth" is 300%, so whatever the current amount, increased by 3 times as much is 4 times the current amount, or a quadrupled amount.
Can you please add a picture of the problem or type all the measurements and information?
2 or 3 I think is the answer for number 5
Consecutive odd numbers are 2 apart
they are
x,x+2,x+4,x+6
10+2x=x+4+x+6
10+2x=2x+10
x=x
true
any consecutive odd integers will work
1,3,5,7 works
3,5,7,9 works
etc
