In arithmetic and algebra the seventh power of a number n is the result of multiplying seven instances of n together. So:

n7 = n × n × n × n × n × n × n.

Seventh powers are also formed by multiplying a number by its sixth power, the square of a number by its fifth power, or the cube of a number by its fourth power.

The sequence of seventh powers of integers is:
