Answer:
B. 3
Explanation:
2 + 3 = 5
5 + 3 = 8
8 + 3 = 11
This is how you find the common rate between a sequence of numbers. If you find how to get to on number, you see if it works on another, and so on. If it does, that is the rate.
To solve this you can make a perportion
252 x
----- = -----
350 100
and solve 252 times 100/350=72
252 is 72% of 350
