After the initial number 3, the next number is generated by adding the square of numbers increasing by one at each step and starting with 12.

3 + 12 = 4

4 + 22 = 8

8 + 32 = 17

17 + 42 = 33....and so on

The series formula is U(n) = n3/3 - n2/2 + n/6 + 3, which can also be written as :-

3 + n/6(2n2 - 3n + 1) = 3 +n/6(2n - 1)(n - 1)

Q: What is the pattern rule for this pattern 3-4-8-17-33?

To guess a rule for a pattern, you need several numbers, not just one. Of course, you can invent any rule, for example, "all numbers in the sequence are equal to -4", or some more complicated rule.

A single number, such as 24102882, does not establish a pattern!

An exception does not obey a rule or pattern. Often, the only way to identify an exception is to know the rule or pattern that should be expected.

there is no rule i think my teacher said its about the pattern

A single number, such as 24102882, does not establish a pattern!

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'.

The rule is multiply the previous term by -1 to find the next term.

A pattern that not only continue the pattern but find the value for the given term in the pattern.

One number, such as 2511234795, does not make a pattern.
