Find the common difference between terms of the function f(n)=4n+6

  4

Step-by-step 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.

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.
