Question

The common difference for the following A.P. is :3/4,1/4,-1/4,-3/4​

Answer 1

Answer:

- 1/2

Step-by-step explanation:

common difference (d) = 1/4 - 3/4

= - 2/4

= - 1/2

Answer 2

Common difference d = a2 - a1

= a3 - a2

$a_{2} - a_{1} = \frac{1}{4} - \frac{3}{4} \\ = \frac{ - 2}{4} \\ = \frac{ - 1}{2}$

$a_{3} - a_{2} = \frac{ - 1}{4} - \frac{1}{4} \\ \: \: \: \: \: \: \: \: = \frac{ - 2}{4} \\ = \frac{ - 1}{2}$

The common difference d is -1/2.
