How do you find the rule of the sequence if the 2nd term is 40057.07 and the 5th term is 19192.53

depends what kind of a sequence you have
1. if it is arithmetic
solve a+d= 40057.07 and
a+4d = 19192.53
2. if geometric
solve ar = 40057.07 and
ar^4 = 19192.53
Of course the sequence could some type of harmonic, etc
in other words, there is not enough information
