AP2 - AP - Complete The Series (Easy)

no tags 

Arithmatic and geometric Progressions are 2 of the well known progressions in maths.

Arithmatic progression(AP) is a set in which the difference between 2 numbers in constant. for e.g., 1, 3, 5, 7, 9 .... In this series the difference between 2 numbers is 2.

The task here is very simple indeed.

You will be given the 3rd term , 3rd last term and the sum of the series. You need print length of the series & the series.


First line will contain a number indicating the number of test cases.

Each of the following t lines will have 3 number '3term' ,'3Lastterm' and 'sum'

3termĀ  - is the 3rd term in of the series and

3LasttermĀ  - is the 3rd term in of the series and

sum - is the sum of the series.


For each input of the test case, you need to print 2 lines.

First line should have 1 value - the number of terms in the series.

2nd line of the output should print the series numbers separated by single space.


3 8 55

1 2 3 4 5 6 7 8 9 10


  • In all the test cases, all the series elements are positive integers.
  • The series will have at least 7 elements.
  • number of test cases <=100.
  • All the numbers will fit in 64 bits (long long in C)

strict timing i wud say

Same solution got TLE in JAVA. Got AC in C++

Abhishek Deora: 2014-12-08 16:03:50

dont print \n in the end ... i got many wrong answers bcoz of dat .

PRAFFUL MEHROTRA: 2014-12-02 11:51:25

AC in first!!

Akshay Madan: 2014-11-03 17:13:07

this problem is not for java

shobhit kumar: 2014-10-27 15:08:48

easy one AC in first :)

Anup AK: 2014-10-26 21:48:50

used long long int and get AC..

Amit Jaiswal: 2014-10-04 13:27:56

for case where n=5
exa 11 11 55
mulitple series possible
1 6 11 16 21
3 7 11 15 19
what to do??
