at up the digits in the number and if the sum is a multiple of three then it means that 3 can go into the number.
eg. the number 27... 2+7=9 and 9 is a multiple of three so 3 can go into 27
3*9 =27

In any division sum, such as 12 / 3 = 4, the number 12 is the dividend. The number 3 is the divisor, while the answer, 4, is the quotient.

If the sum of the digits in a number is divisible by 3, then the original number is divisible by 3.
In any division sum, for example, 12 / 4 = 3, the divisor is the second number - the one that the number is divided by.
Rule: If it is divisible by 2 and by 3Numbers are divisible by 6 if they are divisible by 3 and 2. Therefore, for example, since 18 is divisible by 3 and 2, it is also divisible by 6.The divisibility rule for 6 is, it can go into the number if 2 and 3 can also.

Multiply by 3 !
Divide 7 by 3, using integer division. Write the result (which must be an integer) as the whole number. Write the remainder as the numerator, over the number 3 which is the denominator.
[Impossible].
The answer depends on which number is missing. Even if the location of the gap is know, there are infinitely many possible solutions. The solutions listed below are polynomials of the lowest degree. First: 5 using the rule Un = (-4n3 + 48n2 - 128n + 99)/3 Second: 0 using the rule Un = (-7n3 + 84n2 - 209n + 138)/6 Third: 21.666 (recurring) using the rule Un = (3n3 - 23n2 + 84n - 61)/3 Fourth: 50 using the rule Un = (-11n3 + 90n2 - 121n + 48)/6 Fifth: 65 using the rule Un = (-4n3 + 36n2 - 44n + 15)/3
