What are the first four terms of the sequence represented by the expression n(n-1)-5?
No dude, I'm pretty sure the answer is D.
Y’all realize everybody has different tests right? You need to find a answer from each question
The choices are
-7,-5,-3,1
-5,-10,-15,-20
0,2,6,12
-5,-3,1,7
I don't understand how to do this at all. Please help!
I think the answer is
-5,-3,1,7 for question 3
Anyone knows the full test??
Y'all do know the test changes right?
The general term is
Tn = n(n-1)-5
So, for n=1,2,3,4,5,... replace each n by the given value. That gives
T1 = 1(0)-5 = -5
T2 = 2(1)-5 = -3
T3 = 3(2)-5 = 1
and so on
I am confused... is that the equation n(n-2)-3??? so would the answer be -5, -2, 2, 4??
The answer to this question is D! Thank you Steve
