Write a function rule for our pattern. 84, 90, 96, 102, 108, …. you may use f(x) or the explicit formula. use an for the explicit formula.

For the given sequence, the function rule is f(x) = 84 + 6(n-1) where 'n' represents the number of the term in the sequence.

Step-by-step explanation:

For any given sequence, you need to first find the pattern, or relationship between the numbers.  In this case, you can see that the numbers increase by six each time.  The general formula for an arithmetic sequence, also called explicit formula, is a(n) = a(1) + d(n-1) where a(n) represents the term in the sequence; a(1) is the first term in the sequence; d=the common difference; and n=term number.  When we plug in the values from the question a(1) = 84 and d = 6 to get our final equation.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
