Is this sentence correct?

"The possible ratios for the predictor formulae are w=0.1, w=0.2 and w=0.3. Therefore by substituting these possible ratios into the equations (21) through (32), producing the predictor formulae of ABC method. Thereby, those formulae in (18) are applied by taking p=2, q=6 and the coefficients will then be tabulated in Tables 7 to 16."

*Those formulae actually is general formula of ABC method.*

Thanks a lot...
