Answer:
13
Explanation:
T(n) = n² + 4
Put n as 3 to find the third term.
T(3) = (3)² + 4
Solve for the powers.
T(3) = 9 + 4
Add the terms.
T(3) = 13
If we are trying to find the 3rd term of this specific sequence, then we simply plug in 3 as n.
However, this isn't proper notation for an arithmetic or geometric sequence.
