Motion in A Straight Line

Question: A point moves with uniform acceleration and \[{v_1},\,{v_2}\] and \[{v_3}\] denote the average velocities in the three successive intervals of time \[{t_1},\,{t_2}\] and \[{t_3}\]. Which of the following relations is correct



1) \[({v_1} - {v_2}):({v_2} - {v_3}) = ({t_1} - {t_2}):({t_2} + {t_3})\]
2) \[({v_1} - {v_2}):({v_2} - {v_3}) = ({t_1} + {t_2}):({t_2} + {t_3})\]
3) \[({v_1} - {v_2}):({v_2} - {v_3}) = ({t_1} - {t_2}):({t_1} - {t_3})\]
4) \[({v_1} - {v_2}):({v_2} - {v_3}) = ({t_1} - {t_2}):({t_2} - {t_3})\]
