Question

Math help pleaseeeeeeeeeeeeeeeeeeeeeeee

Answer 1

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

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
