Answer:
Required rule for is .
Step-by-step explanation:
Given that,
From the question: we have to write the term of Arithmetic sequence.
Arithmetic Sequence or Arithmetic progression (A.P) : It is a sequence which possess that difference between of two successive sequence is always constant.
where, is the first term of A.P
is the common difference.
is the last term or general term.
The above sequence to be in A.P then their common difference should be equal.
Now, Formula of General Term is
So,
Substituting the value of we get,
Then General term () of given data is
Therefore, Required rule for is .

Answer:
The virtical angle theorem is that virtical angles are congruent, or equal. A vertical angle is like the angles in an X. The opposite angles are congruent, like in the picture, it is the unknown angle and the angle touching it.
Answer: Our required probability is
Step-by-step explanation:
Since we have given that
Number of red envelopes = 3
Number of blue envelopes = 3
Number of green envelopes = 1
We need to select 3 envelopes in such a way that at least one envelope is a red.
So, it becomes,
Hence, our required probability is
