Number sequences
A number sequence is an ordered list of terms. To continue a sequence, find a rule connecting consecutive terms. The rule may involve constant increase or decrease, multiplication, division or a repeating pattern of operations.
How can the rule be found?
- Calculate differences between consecutive terms.
- If differences vary, check multiplication or repeating operations.
- Test the rule on every given term, not only the first two.
A missing term can sometimes be found more easily by working backwards with an inverse operation. Several rules may fit only a few numbers, so select the simplest rule that matches the complete sequence shown.

Combinatorics is the branch of mathematics concerned with the counting, arrangement, and organization of objects or elements into sets, especially when the exact details of each object are less important than the overall assessment of the structure or pattern.<br /><br /> Probabilities, on the other hand, relate to the likelihood or chance of events. It is a branch of mathematics that deals with the amount of uncertainty or probability. It involves calculations that estimate the probability of different outcomes under certain assumptions or conditions.

What are fractions and what are they used for?<br />Fractions are mathematical phenomena that represent a part of a whole. They consist of two numbers: the numerator (the number at the top) and the denominator (the number at the bottom), separated by a horizontal line. The numerator represents the part we are considering, and the denominator represents all the equal parts that make up the whole.
