Final answer:
To extend a series in a worksheet using Autofill from cell A4 to A33, select the cell, drag the fill handle from the corner, and the series will automatically be populated. This is useful for dates, times, numbers, or formulas following a predictable pattern.
Step-by-step explanation:
To use Autofill to extend a series in a worksheet, you begin by selecting the cell or cells that contain the starting data, which in this instance is cell A4. Place your cursor over the bottom right corner of the cell or cells until it turns into a small cross. Then, click and drag down to the desired cell, which is A33 in this case. Autofill will automatically continue the series for you.
For example, if you start with a number or date in cell A4, Autofill will increment it sequentially down to cell A33. If A4 contains a formula, Autofill will adapt that formula for each subsequent cell. This feature is particularly useful when working with data that follows a predictable pattern such as dates, times, consecutive numbers, or repeated text sequences.
When dealing with tables and calculating values, such as in exercises 9 and 36, Autofill can be used to complete the pattern of calculations across multiple cells. By dragging the fill handle across the relevant cells, your table will be populated based on the initial formula, ensuring consistency and saving time.
