khoảng cách = 3

số cuối - số đầu = (91 - 1)  x 3 = 270 

số cuối = 270 + 7 = 297

tổng = (số đầu + số cuối) x số số hạng : 2 = (7 + 297 ) x 91 : 2 = 13832

91 số thì có 90 khoảng cách (3).Vậy số cuối là:               

                                                                    90x3+7=277

Tổng của dãy số trên là:

                                                     (277+7)x91:2=12922
