1. I'm assuming you meant to type 0.2, 0.6, 1, 1.4...

In that case, it is increasing by 0.4, so the next three would be:

0.2 + (4-1)(0.4) = 1.8...

=> 1.8, 2.2, 2.6.

2. Here it's reducing by 0.25, so start with:

4 + (5-1)(-0.25) = 3...

=> 3, 2.75, 2.5

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
