Question
For the AP 3, 1, -1, -3 ......, write the first term and the common difference.
✓
Answer
3, 1, -1, -3...
First term = a= 3,
Common difference (d) = Second term - first term = Third term - second term and so on
Therefore, Common difference (d) = 1 - 3 = -2
First term = a= 3,
Common difference (d) = Second term - first term = Third term - second term and so on
Therefore, Common difference (d) = 1 - 3 = -2
