okay maths question jumpscare

but does anyone know why the average between two numbers goes up when the numbers get bigger? I feel like it's obvious but basically me and my sister were up so late last night trying to work it out (context in the tags)

tl;dr: if the age difference between two people stays the same constantly, why does the average age between them go up as they get older?

#so it started bc as a joke we always say how old we were in a certain year as like ''we were an average of [whatever]''#based on how e.g. this year i started as 22 and she ends the year as 22 so although we're never the same age at the same time #we'll still experience the same age within the same year. so this year we'll be like ''we're an average of 22''#but then we were thinking what actually is the average of our ages?#and then we spent ages trying to work it out for no reason #so we've got 505 days between when we were born #so surely half of that must be the centrepoint of our age difference #but that would only truly apply to when she was born so we'd have to add whatever our current ages are to it #so like the amount of days between just our birthdays is 140 apparently #so say on her 22nd birthday i was 23 and 140 days #but yeah basically we ended up with the formula:#252.5 + (365 x her age)#and that'll give us the number of days between our current ages at any point #although it's not fully accurate bc obviously she's not gonna be exactly 22 or 21 everyday #so maybe the formula should be something like #252.5 + just the amount of days she's been alive #either way it gets the right answer #but then basically we were wondering why the average goes up when we get older and are we stupid or is there a recognised reason lol #like we get Why is goes up but we just wanna know if there's like a formula #so basically #why does the average between two people's ages go up as the people get older?#ramble
