Question
The common difference of the Arithmetic Sequences …. -4 , -2 , 0 , 2 …. Is
- 2
- -2
Hint:
An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
The correct answer is: 2
We have to find the common difference of the given AP, -4,-2,0,2,...
We have, d = -2 - (-4) = -2 + 4 = 2.
Hence, the correct option is (a) .
The constant difference between two consecutive terms of an AP is called the common difference. The nth term of an arithmetic sequence is given by. an = a + (n – 1)d.
