    Answer: 145.
    Explanation: Sum of the squares of the digits of the previous number.
    5×5=25
    (2×2)+(5×5)=29
    (2×2)+(9×9)=85
    (8×8)+(5×5)=89
    (8×8)+(9×9)=145

    (1×1)+(4×4)+(5×5)=42

  • Confused says:

    125.
    25 – 5 = 20
    25 + 4 = 29
    85 – 29 = 56
    85 + 4 = 89
    56 – 20 = 36
    89 + 36 = 125
