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.
