Answer: The total number of logs in the pile is 6.
Step-by-step explanation: Given that a stack of logs has 32 logs on the bottom layer. Each subsequent layer has 6 fewer logs than the previous layer and the top layer has two logs.
We are to find the total number of logs in the pile.
Let n represents the total number of logs in the pile.
Since each subsequent layer has 6 fewer logs then the previous layer, so the number of logs in each layer will become an ARITHMETIC sequence with
first term, a = 32 and common difference, d = -6.
We know that
the n-th term of an arithmetic sequence with first term a and common difference d is
![a_n=a+(n-10)d.](https://tex.z-dn.net/?f=a_n%3Da%2B%28n-10%29d.)
Since there are n logs in the pile, so we get
![a+(n-1)d=2\\\\\Rightarrow 32+(n-1)(-6)=2\\\\\Rightarrow 32-6n+6=2\\\\\Rightarrow 6n=36\\\\\Rightarrow n=6.](https://tex.z-dn.net/?f=a%2B%28n-1%29d%3D2%5C%5C%5C%5C%5CRightarrow%2032%2B%28n-1%29%28-6%29%3D2%5C%5C%5C%5C%5CRightarrow%2032-6n%2B6%3D2%5C%5C%5C%5C%5CRightarrow%206n%3D36%5C%5C%5C%5C%5CRightarrow%20n%3D6.)
Thus, the total number of logs in the pile is 6.
