👉 In the context of mathematics, a "rachiform" is a type of polynomial that has an odd number of terms. This means that each term in the polynomial appears exactly once except for the last one, which appears twice. For example, consider the polynomial: 1 + 2x + 3x^2 + 4x^3 + ... The first three terms are all even (1, 2, and 4), while the fourth term is odd (3). Therefore
