Question

Using the explicit formula, find the 3rd term f(n)=5+4(n-1)

Answer 1

13

Step-by-step explanation:

The explicit formula of a sequence is given below:

`f\mleft(n\mright)=5+4\mleft(n-1\mright)​`

When n=3

`\begin{gathered} f\mleft(3\mright)=5+4\mleft(3-1\mright)​ \\ =5+4(2) \\ =5+8 \\ =13 \end{gathered}`

The 3rd term of the sequence is 13.
