Part A
The number of walking planks is given by the series
5, 9, 13, ...,
This is an arithmetic series with
a = 5, the first term
d = 4, the common difference
On the n-th day, the number of walking planks is
![a_{n} = 5 + 4(n-1)](https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%205%20%2B%204%28n-1%29)
Answer:
![a_{n} = 5 +4(n-1)](https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%205%20%2B4%28n-1%29)
Part B
On the 12-th day, the number of walking planks is
![a_{12} = 5 +4(12-1) = 5 +44 = 49](https://tex.z-dn.net/?f=a_%7B12%7D%20%3D%205%20%2B4%2812-1%29%20%3D%205%20%2B44%20%3D%2049)
