when finding consecutive odd integers why would you use n, n+2 and n-2 rather than n, n+2 and n+4

• trig -

you should use neither...you should use 2n+1,2n+3, and 2n+5 to get odd integers

• trig -

you could use either,
(n-2) , n , (n+2) or
n , n+2, n+4 or
2n+1, 2n+3, 2n+5 or
12n+34. 12n+36 , 12n+38 or
...

since odd numbers are 2 apart, any of the above would work.
the advantage of using n-2, n, and n+2 is that when they are added, the constants would drop out
