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 $(d) = 1 - 3 = -2$
