Respuesta :
The denominators are being added by 4,
11 + 4 = 15
15 + 4 = 19
19 + 4 = 23
The next number should be
23 + 4 =
1/27
11 + 4 = 15
15 + 4 = 19
19 + 4 = 23
The next number should be
23 + 4 =
1/27
The next denominator is added by 4.
The next on the series = 1/(23 + 4) = 1/27
The next on the series = 1/(23 + 4) = 1/27
