Let us study the sequence and series formula. All of these calculations are similar to studying numeric patterns and extending them or summing them up to visualise a future score, which is some steps further in the extension of the sequence that was observed from past scores. One simple example is score prediction, required run rate, projected score, etc. Sequences and series are immensely useful when trying to do predictive or projective calculations. We have to just put the values in the formula for the series. Suppose we have to find the sum of the arithmetic series 1,2,3,4. Series and sequence are the concepts that are often confused. Whereas, series is defined as the sum of sequences, which means that if we add up the numbers of the sequence, then we get a series.Įxample: 1+2+3+4+.+n, where n is the nth term. x n, where 1,2,3 are the positions of the numbers and n is the nth term. We can commonly represent sequences as x 1, x 2 ,x 3. This mathematical representation of such patterns is studied under sequence and series.Īny pattern when laid out in numbers and separated by commas is known as a sequence. All of these can be determined and represented mathematically. Graphs, geometry, mandalas, snail shells, flower petals, and so on. Think of patterns that you see around you in daily life.

We can define a sequence as an arrangement of numbers in some definite order according to some rule.
