1. The problem asks to find the sum of all sums and provide formulas. 2. To clarify, the sum of a sequence of numbers can be found using different formulas depending on the type of sequence. 3. For an arithmetic series (where each term increases by a constant difference $d$), the sum of the first $n$ terms is given by the formula: $$S_n = \frac{n}{2} (2a_1 + (n-1)d)$$ where $a_1$ is the first term. 4. For a geometric series (where each term is multiplied by a constant ratio $r$), the sum of the first $n$ terms is: $$S_n = a_1 \frac{1-r^n}{1-r}$$ if $r \neq 1$. 5. If the problem involves summing all sums, it might mean summing multiple series or sums of sums, but since no specific sequences are given, we focus on these general formulas. 6. To sum multiple sums, you add their results. For example, if you have sums $S_1, S_2, ..., S_k$, the total sum is: $$S_{total} = \sum_{i=1}^k S_i$$ 7. Without specific sequences or numbers, this is the general approach and formulas to use. Final answer: Use the arithmetic sum formula $$S_n = \frac{n}{2} (2a_1 + (n-1)d)$$ and geometric sum formula $$S_n = a_1 \frac{1-r^n}{1-r}$$ to find sums, then add all sums together if needed.
