[lunar plover]

use this to find the (2n + 1)st term

then S(2n + 1) is S(2n) + ((2n + 1)st term)

[meager mulch]

What how

[lunar plover]

do you know what the S stands for

[meager mulch]

Yes summation

[lunar plover]

so you know S is a sum of a sequence A right

[meager mulch]

Yes

[lunar plover]

so S(2n + 1) = S(2n) + A(2n + 1)

that is what I mean by (2n + 1)st term, forgot to say

[meager mulch]

Ohh

What's A

The series?

[lunar plover]

.

usually the A is lowercase

[meager mulch]

This right

[lunar plover]

so Sn = a1 + a2 + ... + an

[meager mulch]

Ohh understood thanks

[lunar plover]

that doesnt answer your question

yea

[meager mulch]

wait nvm
