Is the address 7b invalid regarding cell references?

Lubov Fominskaja [6]

Answer:

It is not valid

Explanation:

I'll assume the question relates to cell referencing in Microsoft Excel.

To reference a cell in Excel, we make use of the following steps:

Write out the cell column name first
Followed by the row number

7b implies that, the row number first, followed by the column name; this doesn't follow the naming convention of cells.

Hence, 7b is invalid.
