5*3^n
A.15,30,45,60***
B.5,15,45,135
C.0,15,45,135
D.15,45,135,405
I need help plz answer my question
If n is supposed to be that series, then you do
5*3^n
5*3^1 = ?
5*3^2 = ?
5*3^3 = ?
5*3^4 = ?
etc.
What you must do is evaluate the 3^n part and multiply by 5.
5*3^1 = 5*3 = 15.
etc.
Yes, D is correct.
Is it B,C, or D plz help me
If n is supposed to be that series, then you do
5*3^n
5*3^1 = ?
5*3^2 = ?
5^3^3 = ?
5^3^4 = ?
etc.
What you must do is evaluate the 3^n part and multiply by 5.
5^3^1 = 5^3 = 15.
etc.
So d?
Your question isn't very clear. What's n?
Then what is it I am so confused
To find the value of the expression 5*3^n, you need to substitute different values of n and calculate the result. Let's try substituting some values and see which option matches the outcome:
For n = 0, the expression becomes 5*3^0 = 5 * 1 = 5.
For n = 1, the expression becomes 5*3^1 = 5 * 3 = 15.
For n = 2, the expression becomes 5*3^2 = 5 * 9 = 45.
For n = 3, the expression becomes 5*3^3 = 5 * 27 = 135.
From these calculations, we can see that the correct option is D.15,45,135,405, as it matches the outcomes of the expression for n = 0, 1, 2, and 3.
If n is supposed to be 1,2,3,4 sequentially, your answer of A is not right.
If you don't know what n is, how did you arrive at A as being the best answer? Guessed, I suppose.
I think n is supposed to 1, then 2, then 3, then 4, etc. so that you have a series of answers.
