if the letter n represents a positive integers {1,2,3,4. . .}, write algebraic expression for each of the following

Question

an even integer

Answer 1

To represent an even integer using the positive integer variable \( n \), you can use the expression:

\[ 2n \]

Here, multiplying \( n \) (which represents any positive integer) by 2 guarantees that the result will always be an even integer, since even numbers are defined as multiples of 2.
