The list of numbers – 10, – 6, – 2, 2,… is(A) an AP with d = �

1.	The list of numbers – 10, – 6, – 2, 2,… is(A) an AP with d = – 16(B) an AP with d = 4(C) an AP with d = – 4(D) not an AP
Answer» (B) an AP with d = 4 Explanation: According to the question, a_{1 =} – 10 a_{2 =} – 6 a_{3 =} – 2 a_{4 =} 2 a_{2 –} a_{1 =} 4 a_{3 –} a_{2 =} 4 a_{4 –} a_{3 =} 4 a₂ – a_{1 =} a_{3 –} a_{2 =} a_{4 –} a_{3 =} 4 Therefore, it’s an A.P with d = 4

The list of numbers – 10, – 6, – 2, 2,… is(A) an AP with d = – 16(B) an AP with d = 4(C) an AP with d = – 4(D) not an AP

Answer»

(B) an AP with d = 4

Explanation:

According to the question,

a_{1 =} – 10

a_{2 =} – 6

a_{3 =} – 2

a_{4 =} 2

a_{2 –} a_{1 =} 4

a_{3 –} a_{2 =} 4

a_{4 –} a_{3 =} 4

a₂ – a_{1 =} a_{3 –} a_{2 =} a_{4 –} a_{3 =} 4

Therefore, it’s an A.P with d = 4
