an AP with d = – 16
an AP with d = 4
an AP with d = – 4
not an AP
उत्तर
The list of numbers – 10, – 6, – 2, 2,... is an AP with d = 4.
Explanation:
According to the question,
a1 = – 10
a2 = – 6
a3 = – 2
a4 = 2
a2 – a1 = 4
a3 – a2 = 4
a4 – a3 = 4
a2 – a1 = a3 – a2 = a4 – a3 = 4
Therefore, it’s an A.P with d = 4.
