5-5^2 = 5-25 =-20
The fifth term is just when n=5 I believe.
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 aₙ = 5 - n², we substitute n = 5 into the equation.
a₅ = 5 - (5)²
= 5 - 25
= -20.
Therefore, the fifth term of the sequence is -20.
So, your belief that the answer is d) -5 is incorrect. The correct answer is b) -20.
