Pascal's triangle the rules of Pascal's triangle, but double the one on the left before adding. This results in: The other way of manufacturing this triangle is to start with Pascal's triangle and multiply each entry by 2, where k is the position in the row of the given number. For example, the 2nd value in row 4 of Pascal's triangle is 6 (the slope of 1s corresponds to the zeroth entry in each row). To get the value that resides in the corresponding position in the analog triangle, multiply 6 by 2 = 6 × 2 = 6 × 4 =
