why are you leaning towards (d)? Just guessing? You should shjow your work, so we can help you see where you went wrong (if you did)
just plug in 1,2,3,4 for n.
1(1-1) - 4 = 0 - 4 = -4
Looks like (c) already, but you might want to check the other terms to be sure.
hi! i was wondering if i could get help on this question as soon as possible.
What are the first four terms of the sequence represented by the expression n(n - 1) - 4?
a) -2, 2, 6, 10
b) -3, 0, 3, 6
c) -4, -2, 2, 8
d) -5, -4, -2, 6
i'm leaning towards d, but i'm not sure if i'm right because i'm quite bad at math. please help as soon as possible!
