 8 Is it possible to have a rule which generates: 2, 4, 6, 8, 10, 12, 14, 16, -23? 7 Prove by Mathematical Induction: $1(1!) + 2(2!) + \cdot \cdot \cdot +n(n!) = (n+1)!-1$ 3 Find the Sum $1\cdot2+2\cdot3+\cdots + (n-1)\cdot n$ 3 If $f(x) = x-5$ and $g(x) = x^2 -5$, what is $u(x)$ if $(u \circ f)(x) = g(x)$? 2 Induction Proof: $\sum_{i=1}^{n+1} i \cdot 2^i = n \cdot 2^{n+2}+2$
