1) Algebra Formulas
2) Geometry Formulas

In any Music, March past or any other rhythmic work we observe that these tasks are done with  proper sequence. Let us take a very simple example of our day today work. In night we sleep, then in the morning we wake up, then we finish our morning tasks. We take our breakfast then go to school/office/business-spot/work-place. We take lunch in the afternoon outside those who go out else at home/hotel. Then we come home in the evening then do some entertainment, watch TV or play some computer Games then diner then go to bed to sleep. This cycle will be maintained on week days. This one may be an example of sequence if we say that each and every task is done very well.  

Harmonic Motion, Sewing needle, Swing of Pendulum are also the examples of sequence.

1, 3, 2, 1, 3, 2, 1, 3, 2, 1, 3, 2, 1, 3, 2, 1, 3, 2, 1, 3, 2, 1, 3, 2, 1, 3, 2, 1, 3, 2....... is also an example of sequence. here the three numbers 1, 3, 2 are getting repeated several times.

Another example will be 1, -1, 1, -1, 1,1, -1, 1, -1, 1,1, -1, 1, -1, 1,1, -1, 1, -1, 1....... 
(The position of the Sewing Needle)

In Math, we will study three types of sequences. 

1) Arithmetic Sequence (Arithmetic Progression) Written as A. P.
2) Geometric Sequence (Geometric Progression) Written as G. P.
3) Harmonic Sequence (Harmonic Progression) Written as H. P.

Details of Arithmetic Sequence (Arithmetic Progression):

When a constant Number is added in the previous term we get our term and the same procedure is done for all new succeeding term is called Arithmetic Sequence or Arithmetic Progression.
