Answer:

4

Explanation:

The difference between term n+1 and term n (for any n) is ...

f(n+1) - f(n) = (4(n+1) +6) - (4n +6)

= 4n + 10 - 4n -6

= 4

This is the common difference between any pair of adjacent terms.

_____

You can also recognize that this value is the value of the coefficient of n, so can you read the answer directly from the function definition.
