What are the first four terms of the sequence represented by the expression n(n-2)-3?
-5, -2, 1, 4
-4,-3, 0, 5
3, 0, 3, 6
2, 0, 2, 4
I believe it's C?
To find the first four terms of the sequence represented by the expression n(n-2)-3, we substitute values for n.
Let's plug in the values and calculate the corresponding terms:
For n = 1:
1(1-2) - 3 = -2 - 3 = -5
For n = 2:
2(2-2) - 3 = 0 - 3 = -3
For n = 3:
3(3-2) - 3 = 3 - 3 = 0
For n = 4:
4(4-2) - 3 = 8 - 3 = 5
The resulting terms are: -5, -3, 0, 5.
Comparing these with the options provided, we can see that the correct answer is option B: -5, -3, 0, 5.
Therefore, your initial belief was incorrect.
