tentukan u25 dari 3,5,7,9......

2 Jawaban

  • 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51

    Rumus u25 = n x 2 + 1
    u = 25 x 2 + 1
    u = 51

  • a=3

    b= u2-u1 = 5-3 = 2

    u25 = a+24b

    u25 = 3 + 24.2

    u25 = 3 + 48

    u25 = 51
