When I did a proofreading ex., I found that the answer is >>in average<<.The sentence is showed below

I would like to congratulate all of you because the 20 km sponsored walk raised much more money this year than last

year.This is because many more students took part this year than last year and each of them was able to get more

in

sponsors

Is it right?? in average?? What is the difference between "in average'' & "on average"???

**20-km**sponsored walk raised much more money this year than lastyear. This is because many more students took part this

**year, and**each of them was able to get more**on average from their sponsors.***Is it right??*-- It is right as corrected. The ending of the original sentence is indecipherable.*in average??-*- No, not possible here.*What is the difference between "in average'' & "on average"?*-- The first is not English in this situation, though I suppose I could construct another kind of sentence in which is is OK: '*In average homes there are 2.5 TV sets*'.

As to your example,In >> average homes<< there are 2.5 TV sets.

Is that "average" is describing the homes?
