Answer:

The set Builder Notation is:
\n\in N\

Explanation:

Consider the provided set:


\{5,5^2,5^3,5^4...\}

The Set-Builder Notation is a simple way to write sets, often sets with an infinite number of elements.

For example: The set {x : x > 0} is read as "the set of all x such that x is greater than 0.

The above set can be written as:


\{5^1,5^2,5^3,5^4...\}

We can observer the base is 5 and the exponent is increasing from 1 to ∞.

Thus, the set Builder Notation is:
\5^n

Where, N is set of Natural numbers i.e. 1, 2, 3,.....
