175 is the ___th term of 15, 20, 25,30... and is solved by the equation 175=15+(n-1)5. When I learned this there was something simple I used to do to solve for n and it was super easy. Now I can't find it. I think it had something to do with division.
-
175 = 15+ (n-1)5
175 = 15 + 5n - 5
175 = 10 + 5n
165 = 5n
165/5 = 5n/5
33 = n
I hope it helps!

Subtract 15 from both sides of the equation:
175-15=160
Now try to see where (n-1)*5 = 160
First, Divide both sides by 5 to get:
(n-1)=32
then add one to both sides to get n=33.
175-15=160
Now try to see where (n-1)*5 = 160
First, Divide both sides by 5 to get:
(n-1)=32
then add one to both sides to get n=33.

first distribute 5 to n and -1... so 175= 15 +5n-5
next combine like terms... 175= 10 + 5n
subtract 10 from 175... 165= 5n
divide by 5 to get n alone... 33=n
so 175 is the 33rd term in the sequence.
