What is the fifth term of the sequence
a sub n=5-n^2?
a)-11
b)-20
c)-7
d)-5
what is your thinking on this?
I think that the answer is d, -5, that seems to be the most reasonable answer.
To find the fifth term of the sequence, we need to substitute the value of n as 5 in the given formula a sub n = 5 - n^2.
So, a sub 5 = 5 - (5)^2
= 5 - 25
= -20
Therefore, the fifth term of the sequence is -20.
The correct answer in this case is b) -20.
Please note that your initial selection of d) -5 is incorrect.
