Step 1
We are asked to find a formula for the sum of a sequence that starts with 2, followed by 1, then 8, and so on, up to the nth term. The sequence is not clearly defined, but it seems there might be a typo in the question. Given the pattern 2, 1, 8, it's hard to Show more…

Induction and Recursion
Mathematical Induction
Use mathematical induction in Exercises $3-17$ to prove summation formulae. Be sure to identify where you use the inductive hypothesis. a) Find a formula for $$ \frac{1}{1 \cdot 2}+\frac{1}{2 \cdot 3}+\cdots+\frac{1}{n(n+1)} $$ by examining the values of this expression for small values of $n .$ b) Prove the formula you conjectured in part (a).
Evaluate the expression $a \cdot b^{n-1}$ for the given values of $a, b,$ and $n$. $$ a=1, b=2, n=5 $$
