Question

give sequences series formulas?

Answer 1

Answer:

Step-by-step explanation:

Limit Of An Infinite Geometric Series For a geometric sequence an = a1rn-1, where -1 < r < 1, the limit of the infinite geometric series a1rn-1 = . This is the same as the sum of the infinite geometric sequence an = a1rn-1.

 

Sum Of A Finite Arithmetic Sequence The sum of the first n terms of the arithmetic sequence is Sn = n() or Sn = na1 + (dn - d ), where d is the difference between each term.

 

Sum Of A Finite Geometric Sequence For a geometric sequence an = a1rn-1, the sum of the first n terms is Sn = a1
