The rule is (-2, -5)
Adding 2
2 1 2
To find the nth number that is generated by the rule multiply n by 4 and then add 2.
The rule for 43, 83, 6 is Un = (-117n2 + 431n - 228)/2 for n = 1 , 2, 3, ...
1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
You can always check on the divisibility of a number by dividing it into another number. But if you know the divisibility rules, you can get that information easier and faster.
The rule is (-2, -5)
The divisibility rule for 2 works because the base of our number system, 10, is divisible by 2.
The answer is A = 2.
2+2-2*2/2 = ?
The divisible rule for 2 is if the last digit of the number is 0,2,4,6, or 8. The divisible rule for 3 is if the last 2 digits of the number is divisible by 3,03,06,09,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69,72,75,78,81,84,87,90,93,96, or 99.
The rule for the pattern is y=x+2. That rule is in the table format in which it would originally be in, but the worded rule would be 'It increases by 2 each time'.
2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.
