Answer:
b) For the given explicit definition, t(4) = 8
Step-by-step explanation:
Here, the given expression is:
[tex]t_n = n^2 - 2n[/tex]
Now, we need to evaluate t(4).
Putting the value of n = 4, in the given expression, we get
[tex]t = 4 \implies t_{(4)} = (4)^2 - 2(4)\\= 16 - 8 = 8\\\implies t_4 = 8[/tex]
Hence, for the given explicit definition, t(4) = 8
