K, so, lets add them up
1+2=3
1+2+3=6
1+2+3+4=10
1+2+3+4+5=15
1+2+3+4+5+6=21
1+2+3+4+5+6+7=28
etc
basically
all numbers 'x' such that
x=
and n is the set of all natural numbers
Answer:

O’s home. Wildgrove
Wild grove to lakewood:
21^2 + 72^2 = x^2
441 + 5184 = x^2
5625 = x^2
75 = x
Home to Lakewood: 72
Lakewood to wildgrove: 75
Wildgrove to home: 21
72+75+21= 168 kilometers
