    So we have 1,8,27

    this is obviously not an arythmetic sequence (addition)

    it is a geometric sequence (multiplication and exponents)

    1st term=1

    2nd term=8

    3rd term=27

    I notcie that 8=2^3 and 27=3^3 so therefor

    the nth term is

    n^3

    so 4th term=4^3=64

    5th term=5^3=125

    6th term=6^3=216 etc

    the nth term is n^3
