The eternal struggle between elegant simplicity and mathematical reality! The sequence 1, 2, 4, 8, 16... is clearly a geometric progression where each term is 2 times the previous (2^(n-1)). It's beautiful, intuitive, and makes perfect sense.
But then the teacher hits you with that monstrosity of a formula: a_n = (1/24)(n⁴-6n³+23n²-18n+24). That fourth-degree polynomial is what happens when your professor decides to make your life unnecessarily complicated. The face progression from "I got this!" to "What fresh mathematical hell is this?" is the universal language of every student who's ever been bamboozled by an unexpected answer key.
Fun fact: Both formulas actually give the same sequence values! The polynomial is just an absurdly overcomplicated way to express what 2^(n-1) does with elegant simplicity. Classic case of mathematical trolling.
