A boy runs 1 3/4miles on Tuesday, 2 1/2miles on Wednesday, 3 5/6miles on Thursday, and 2 1/4 miles on Friday. What is his total mileage for last two days?

Well, firstly, inductive reasoning is reaching a conclusion based off of a series of observations. An example is if you noticed that all the pigeons you see are grey and so you make the conclusion that all pigeons are grey. It's a conclusion based off just a few observations, not necessarily true or false. 

Based on that reasoning, I'd say 1 and 4 are inductive reasoning. 2 is deductive reasoning because it's based on a fact, as is 3.
