User:Jan Rider

Aged 60.years. Semi-retired carer in S.London, England. Relatively new to the "digital" age and IT. Have posted general mathematics observations on Physics Forums website about what I now discover are decagonal integers and also prime pairs given by 45r^2+15r +/-1 45r^2-15r +/-1 which have the same potential factors as decagonal integers. I merely wish to give a new sequence which is generated by a quadratic expression related to that for decagonal integers.
