I test my blood pressure w digital bp monitor three times in a row the result are different which is correct reading?

It is not recommended to take your blood pressure three times in a row. Instead, you should wait at least 3-5 minutes between readings to allow your blood pressure to return to its resting state. The first reading is usually the least accurate, as it can be affected by factors such as anxiety, stress, and other activities. The second and third readings are usually more accurate, as they are less likely to be affected by these factors. It is best to take the average of the second and third readings to get the most accurate blood pressure reading.
