The frequency of G3 is 196.00 Hz. What is the frequency of G1, which is two octaves below G3?
49.00 Hz

98.00 Hz

392.00 Hz

784.00 Hz

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Could you make it more clear?
