    Answer: (3) 23
    Explanation:-
    Let the seven consecutive numbers are X , X + 1, X + 2, X + 3, X + 4, X + 5, X + 6.
    The average of seven consecutive numbers = 26
    The total sum of seven consecutive numbers = 26 x 7
    = 182

    Then,
    X + X + 1 + X + 2 + X + 3 + X + 4 + X + 5 + X  +6 = 182
    7 X + 21 = 182
    7 X = 182 – 21
    7 X = 161
    X = 23
    Hence, the smallest integer is 23.
