Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
4.4 pounds $2.35 = $.53 per pound
10 pound $4.99 = $ .49 per pound
2,6,15,31,......
6-2=4=2X2
15-6=9=3X3
31-15=16=4X4
So the next number should be 31+5X5=56
hope this helps :)
