    1) Diketahui :
    U_4 = 110
    U_9 = 150

    Ditanya : U_30 ?

    Jawab :
    U_4 = a + (4-1) b = 110
    = a + 3b = 110
    U_9 = a + (9-1) b = 150
    = a + 8b = 110

    Elminasi
    a = 86 b = 8

    U_30 = 86 + (30-1) 8
    = 86 + 29.8
    = 86 + 232
    = 318

    2) Diketahui :
    U_3 = 9
    U_5 + U_7 = 36

    Ditanya : S_n ?

    Jawab :
    U_3 = a + (3-1) b = 9
    = a + 2b = 9
    U_5 + U_7 = 36
    a + 4b + a + 6b = 36
    2a + 10b = 36
    a + 5b = 36

    Elminasi
    a = 3 b = 3

    Sn= n/2 (a +U_n )
    = n/2 (a + ( a + 9b)
    = 10/2 (3 + ( 3 + 9.3)
    = 5 (3 + (3 +27)
    = 5.33
    = 165
