Answer:
The rule is 3(5)^(n-1) where n is the term number.
Step-by-step explanation:
The constant multiplier = 15/3 = 5.
Checking that this is correct 75/15 = 5, 375 / 75 = 5.
So for term number 1 , the value is 3 , the expanded form is 3 * (5)^(1-1) and the simplified form is 3*5^0 = 3.
Term number 2, the value is 15 , the expanded form is 3 * 5^(2-1) and the simplified form is 3 * 5^1 =15.
The other rows are calculated in the same way.
This is a Geometric sequence with common ratio 5.
The rule for the sequence is 3(5)^(n-1).

Answer:
x = 12
Step-by-step explanation:
Step 1: Define
f(x) = 2x - 7
f(x) = 17
Step 2: Substitute
17 = 2x - 7
Step 3: Solve for <em>x</em>
<u>Add 7 on both sides:</u> 24 = 2x
<u>Divide both sides by 2:</u> 12 = x
Step 4: Check
f(12) = 2(12) - 7
f(12) = 24 - 7
f(12) = 17
