## What is Succession:

succession is **a series of elements, finite or infinite, that follow one after the other in time or space obeying an order**.

Succession comes from Latin *succsessio *composed of the prefix *sub*– indicating ‘below’, *cessus *which refers to the ‘act of walking’ or ‘marching’ and the suffix –*io *indicating action. Therefore, succession means the action and effect of following an already traced path that corresponds to the heirs.

Succession also refers to the replacement or substitution of someone in the performance of a function or position.

The **right of succession** It is the set of assets, rights and obligations that successors inherit after someone’s death. In this case, it is synonymous with inheritance.

## ecological succession

Ecological succession is the process that consists of a set of phases that imply progressive changes over time that will help to form the most stable and complex ecological communities.

Ecological succession implies a chain of species that will succeed one another until reaching the climax community, that is, an environment with sustainable biodiversity.

## number sequence

In mathematics, a number sequence is numbers or mathematical expressions that follow one after the other with established rules. Numerical sequences can be forward (1,2,3,4), backwards (4,3,2,1), alternating (2,4,6,8) or alternating (0,1,0,1) .

A sequence differs from a series because in a series the terms are added (1+2+3+4) and in the sequence they are not.

Number sequences include:

### arithmetic sequences

Arithmetic sequences are distinguished because the difference between each term is constant, therefore, defined with a formula. In the formula, Xn is used to define X as the term and n as the position of the term in the sequence. For example, X5 would be the fifth term of the sequence.

The formula for the arithmetic sequence (3,5,7,9) would be:

See also Arithmetic.

### geometric sequences

In geometric sequences, the terms are calculated by multiplying the previous number, for example (2,4,8,24) would have the following formula:

See also Geometry.

### special successions

Special sequences are those whose terms represent special points within a form, such as:
