Answer:
For n = 1:
1^2 - 2(1) = 1 - 2 = -1
For n = 2:
2^2 - 2(2) = 4 - 4 = 0
For n = 3:
3^2 - 2(3) = 9 - 6 = 3
Therefore, the first three terms of the number sequence are -1, 0, and 3.
To find the 10th term, we substitute n = 10 into the formula n^2 - 2n.
For n = 10:
10^2 - 2(10) = 100 - 20 = 80
Therefore, the 10th term of the number sequence is 80.
