Look at this pattern.
5, 10, 15, 20, 25
Write an expression for the pattern where n= the element number (term number).
A. 5n
B. 5 + n
C. 5n - 5
D. 5n + 5
My answer: A.
Is this right?
of course.
Given the kinds of math questions you have answered, I'm surprised that you would post one like this.
Thanks. I guess I was just doubting myself too much today...
To determine the correct expression for the given pattern, let's analyze the sequence:
5, 10, 15, 20, 25
Notice that each term is obtained by multiplying the element number (n) by 5. For example, the first term (n=1) is obtained by multiplying 1 by 5, resulting in 5. The second term (n=2) is obtained by multiplying 2 by 5, which gives 10, and so on. Therefore, the expression for the pattern would be 5n.
So, your answer of A (5n) is indeed correct. Well done!
