Math help pleaseeeeeeeeeeeeeeeeeeeeeeee

Answer 1

Answer:

b) For the given explicit definition, t(4)  =  8

Step-by-step explanation:

Here, the given expression is:

$t_n = n^2  - 2n$

Now, we need to evaluate  t(4).

Putting the value of n =  4, in the given expression, we get

$t = 4   \implies  t_{(4)} = (4)^2  - 2(4)\\= 16  - 8 = 8\\\implies t_4 = 8$

Hence, for the given explicit definition, t(4)  =  8
