If you repeat the pattern, adding one more zero every time, then no. To qualify as a "repeating decimal", the same digits have to repeat over and over.
It is an indication that the string of digits under the horizontal line repeats for ever.
I believe you are asking about the vinculum, and it is used to indicate one or more digits that repeat their pattern forever.
The line over the digits that repeat in a repeating decimal.
0.076923076923076923076923076923076 ... The digits 076923 repeat over and over.0.076923076923076923076923076923076 ... The digits 076923 repeat over and over.0.076923076923076923076923076923076 ... The digits 076923 repeat over and over.0.076923076923076923076923076923076 ... The digits 076923 repeat over and over.
It is placed over one length of repeating decimal digits.

Bar notation in math terms means that in repeating decimals the line or bar placed over the digits that repeat like 3.666 the bar notation would go over all of the sixes because if the numbers are all the same you just draw the line over the first three numbers that repeat but if you have a number like 0.899899899 then you put the bar notation above the first pattern like .899 and take off the rest until it changes I know this answer is long but after you try it once it will stick with you.
If you repeat the pattern, adding one more zero every time, then no. To qualify as a "repeating decimal", the same digits have to repeat over and over.
The decimal expansion of a rational number always either terminates after finitely many digits or begins to repeat the same finite sequence of digits over and over. As 7.37 terminates after 2 digits it must therefore be rational.
All numbers with a finite number of decimal digits are rational. Some that infinitely many decimal digits are rational as well. If you mean to repeat the pattern, adding one more "1" every time, then no, it is not rational - rational numbers repeat the SAME sequence of digits over and over (for example, 0.1515151515...), at least eventually (they may start with some digits that are not part of the repeating part, such as 3.87112112112...).

It is an indication that the string of digits under the horizontal line repeats for ever.
If you mean to continue the pattern indefinitely, adding more digits, and one more "1" in every cycle, then it is NOT rational. In the case of a rational number, the EXACT SAME group of digits has to repeat over and over (perhaps after some other, initial, digits), for example:0.45113113113113113... Here, the group of digits "113" repeats over and over, so the number is rational.
