    Put n = - 1 on both side

    t (0) = - 2t (-1)

    Now put n=0

    We get t (1) = - 2t (0)

    t (0) = 3/2

    t (1) = - 2*3/2=-3

    Put n=1

    T (2) = - 2*t (1)

    -2*-3

    6

    Now you can easily found

    T (n+1) = - 2t (n)

    t (n+1) is the term after t (n)

    so each term is found by multipilying the prvious term by - 2

    so

    first term is - 3

    2nd is 6

    3rd is - 12

    4th is 24

    5th is - 48

    6th is 96

    7th is - 192

    thos are some terms
