    There are 17 numbers divisible by 3 between 50 and 100.

    Step-by-step explanation:

    Divisibility Rule for 3:

    If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.

    Number divisible by 3 between 50 and 100:

    Minimum number: 51

    Check the sum of digits: 5+1=6  ⇒  6 is divisible by 3

    Maximum number: 99

    Check the sum of the digits:  9+9 = 18  ⇒  1+8 =9  ⇒ 9 is divisible by 3

    Use arithmetic sequence rule:

    an = a₁ + (n-1)(d)

    Where:

    an (last number or term) = 99

    a₁ (first term) = 51

    d (common difference) = 3

    n = number of terms in the sequence, Unknown

    Substitute values:

    an = a₁ + (n-1)(d)

    99 = 51 + (n-1)(3)

    99 = 51-3 + 3n

    3n = 99-48

    3n/3 = 51/3

    n = 17There are 17 numbers divisible by 3 between 50 and 100.
