Find the indicated term of the expression

Find the Fourth term of (6x+5)^5

I always am confused with these because I never know which end I am supposed to start from.  

I guess there is some convention that I can never remember.

The coefficients for a power of 5 are     5C0, 5C1, 5C3, 5C4, 5C5 and these are    1,5, 10,   5,1

So, depending on which end you start from, the forth one is either

$5*(6x)^4*5^1 = 5*6^4x^4*5=25*1296*x^4=32400x^4\\ or\\ 5*5^4*(6x)^1=5^5*6x=18750x$
