The first five terms of a sequence are 7,10, 13 , 16 and 19. which of the following functions define this sequence for all integers n>or equal to 1?

A. f[n]= 3n=7

B.f[n]= 4+3n

C. f[n]= 4[3]^n-1

D.f[n]=7[3]^n-1

Option B is correct.

Step-by-step explanation:

Given:

The given sequence of an AP is.

7,10,13,16,19......

The first term of an AP

And common difference

The function which defined this sequence is;

Now we substitute a and d value in above equation.

therefore, the function for the given sequence for all integers 1 is;  

answer:

what is your question that you ask

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
