Question

Find the common difference of the sequence shown.

1/2, 1/4 , 0, ...

Answer 1

-1/4

Explanation:

Answer 2

-1/4

Explanation:

Given sequence is:

1/2, 1/4 , 0, ...

In order to find the common difference in the terms of a sequence, the preceding term is subtracted from the next term.

For example in the given sequence:

first term will be subtracted from second term and second term will be subtracted from third term

So,

`(1)/(4)-(1)/(2)  \\=(1-2)/(4)\\ =-(1)/(4)\\ Similarly,\\=0-(1)/(4) \\=-(1)/(4)`

The common difference is - 1/4 ..
