How to use SUM function and fill series

Sum Functions are fundamental operations in spreadsheets (Excel, Google Sheets) and programming, used to add values efficiently. Common examples:

SUM(): Adds a range of cells (e.g., =SUM(A1:A10)).
Linear Series: 1, 2, 3... or 5, 10, 15... (use drag-fill)
Custom Lists: Define reusable patterns (e.g., Q1, Q2, Q3...).
