Question

Question 1 (ii)
Which of the following form an AP? Justify your answer.
0, 2, 0, 2, …

Answer 1

$Here,t_1=0,t_2=2,t_3=0and{t}_4=2$
$t_2-t_1=2-0=2$
$t_3-t_2=0-2=-2$
$t_4-t_3=2-0=2$
Clearly, the difference between the successive terms is not the same.
Therefore, the given numbers do not form an AP.
