Find the common difference of the sequence shown.

1/2, 1/4 , 0,

-1/4

Step-by-step 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,

The common difference is - 1/4 ..

-1/4

Step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
