Question 139230: I am in 9th grade advanced algebra 2 and am stumped on 4 of my sequence problems. The other 11 made complete sense, so now I am getting uptight....
The sequences are as follows
0,3,7,12,18,.....
2,-2,-18,-52,-110,-198,.....
4,23,64,133,236,379,568,.....
-5,-9,-19,-35,-57,-85,....
Answer by checkley77(12844)   (Show Source):
You can put this solution on YOUR website! formula is (N+1)
here you have a sequence of +3,+4,+5,+6,+7,+8 +9
0,3,7,12,18,25,33,42
*****************************************
for the next 3 I use a very unconventional method that is too complicated to explain:
please let me know it they are acceptable?????????
2,-2,-18,-52,-110,-198,-322,-488,-702
******************************************
4,23,64,133,236,379,568,809,1108
*****************************************
-5,-9,-19,-35,-57,-85,-119,-159,-205
