creat function called ---- > #def natureSequence(fn, sn, n) :

=====================

Write a function named 'natureSequence' that returns a floating point value

and accepts 3 integer values: 'fn', 'sn', and 'n'

and displays 'n' number of terms in a sequence where the first term is 'fn',

the second term is 'sn', and all subsequent terms are computed from the sum

of the 2 previous terms.

The function returns the value of the last term divided by the 2nd last term.

All terms are separated by a space EXCEPT that there is NO SPACE after

the last term. A new line is output before the function ends.
