Answer» Answer: PUT n=1, the first term is -8–1=-9 Put n=2,the SECOND term is 16–1=-17 like this if you give n=3,4 and the respective TERMS are -25,-33.-41 Sort cut The nth term is given as -8n-1 So the common difference is -8 Add -8 with the first term [-9] you will get 2nd term Adding -8 with the preceding term you will get the next term |
