Question

Write about Different types of progressions and explain the form of terms in each of them

Answer 1

 Arithmetic and geometric are different types of progressions.
example- Write down the 8th term in the Geometric Progression 1, 3, 9, .
 Find the sum of each of the geometric.
another example-0.234523452345... is a recurring decimal because the number 2345 is repeated periodically. 

an arithmetic progression (AP) or arithmetic sequence is a sequence of ... and the common difference of successive members is d, then the nth term of the sequence ( a n {\display style a_{n} . a number common to all of them; that is, infinite arithmetic progressions form a Helly family Kinds of series.

Answer 2

The two different types of progressions are arithmetic and geometric progressions.

Arithmetic Progressions.. If you have the sequence 3, 9, 15, 21, 27 then each term is 6 more than the previous term. This is an example of an arithmetic progression.
Formula... Sn= n/2(a+l)

Geometric progressions.. If you have a sequence such as: 81, 27, 9, 3, 1, 1/3, 1/9,... then each term is one third of the term before.
