Question 134810
may you please help me figure out why this Q = 3N + 5, is the rule to this expression here. When you figure out this problem, may you please tell me how I can write a rule for this? Thank you vey much

N   Q
2   11
4   17
6   23
8   29
10  35

Let's look at the first-two values of N and Q.

What is the value of Q when N is replaced by 2 in the given formula
Q = 3N + 5?  If N = 2, then Q = 11.

LOOK:

Q = 3(2) + 5

Q = 6 + 5

Q = 11

What is the value of Q when N = 4 in the given equation?

If N = 4, then Q = 17.

LOOK:

Q = 3(4) + 5

Q = 12 + 5

Q = 17

The same process applies to all values of N given in the N and Q list above.

The rule is the equation given: Q = 3N + 5.  This equation becomes the key needed to find all the value for Q given in the list.
