00:00 - 00:59 | hi everyone in this question has to write the first five terms of the sequence and obtain the corresponding period even equal to 3 and equal to 3 and minus 1 + 2 for all and greater than one simple problem it is the solution part solution here we have been given a 1 equal to 3 and an equal to 3 and minus 1 + 2 is valid only for greater than let's put an equal to 2 it will be a 23 A1 Plus to know we have the value of a 13 will be in 2222 11 no 83 it will be 382 plus two result be trained to |

01:00 - 01:59 | A to Z lantus to turn out to be 35 now what A4 it will be Re 3 + 2 is equal to 3 235 which will give 1745 it will be free A4 plus two but three in 2017 which will be equal to 3 21 22 23 24 the first five terms are A1 A2 A3 A4 A5 is equal to 3 come 11351 7323 and the series will be series |

02:00 - 02:59 | away the blood 1135 + 17 + 23 + dotdotdot is not final and thank you |

**Representation of sequences and different types of series**

**Definition + algorithm to determine the sequence of AP**

**General term of an AP**

**`n^(th)` term of an AP from the end**

**The `n^(th)` term of the sequence is `3n-2` . Is the sequence an AP. If so; find the 10th term .**

**If first term is 8 and last term is 20 common diffference is 2 . find the value of n when the series are in AP.**

**Which term of the sequence is the first negative term .. `20; 19(1/4);18(1/2);17(3/4).....`**

**Show that the sum of `(m+n)^(th) and (m-n)^(th)` term of an AP is equal to twice the `m^(th)` term ?**

**Show that sum `S_n` of n terms of an AP with first term a and common difference d is `S_n=n/2(2a+(n-1)d)`**

**Find the sum of 20 terms of the AP 1, 4, 7, 10,....**
