What is the fifth term of the sequence
a sub n=5-n^2?
a)-11
b)-20
c)-7
d)-5
I believe that the answer that fits the best is d, but I could be wrong.
To find the fifth term of the sequence, we can substitute n = 5 into the formula a sub n = 5 - n^2:
a sub 5 = 5 - (5)^2
= 5 - 25
= -20
Therefore, the fifth term of the sequence is -20.
Your initial thought was correct. The correct answer is b) -20.
