The condition "seattle" for the field city in a student database is an example of what type of value?

It's a text value

Explanation:

The condition "Seattle" is a text string, a text value, for a database (and most programming languages too).

A text value can contain about any information, it's not restricted and everything you can put in a text format is a valid field value.

It's not a integer value (1,2,3,4) nor a float/decimal value (1.2, 3.4, 3.21345), which are also two other common conditions or types of values stored in a database. Those conditions are more restrictive as to what you can put in those fields. You can put "123" in a text type of value, but you cannot put "and" in a numeric field.
