A pyramid of size n is formed as follows: First, the base of the pyramid consists of n numbers, given as a list: [x_1, x 2, , x_n] The next layer contains n-1 numbers, obtained from adding each pair of adjacent numbers in the lower layer: [x 1 + x_2, x_2 + x_3, , x_(n-1) + x_n] The next layer contains n-2 numbers, obtained from adding each pair of adjacent numbers in the lower layer: [x_1 + 2x 2 + x_3, x_2 + 2x 3 +x 4, , x_(n-2) + 2x_(n-1) + x_n] This process is repeated until the top layer which has only 1 number. Create a function that takes in a list of numbers in the bottom layer and returns the only number at the top layer. For example, we can form a pyramid having a base of [2, e, 2, 1]:

![A pyramid of size n is formed as follows:
First, the base of the pyramid consists of n numbers, given as a list: [x_1, x_2, ., x_n]
The next layer contains n-1 numbers, obtained from adding each pair of adjacent numbers in the lower layer: [x_1 + x_2, x_2 + x_3,
x_(n-1) + x_n]
The next layer contains n-2 numbers, obtained from adding each pair of adjacent numbers in the lower layer: [x_1 + 2x_2 + x_3, x_2 + 2x_3 + x_4, , x_(n-2) + 2x (n-1) + x_n]
This process is repeated until the top layer which has only 1 number.
Create a function that takes in a list of numbers in the bottom layer and returns the only number at the top layer. For example, we can form a pyramid having a base of [2, 0, 2, 1]:
