Write a function rule for the following arithmetic sequence and use it to find the 224th term. show your work. 2, 5, 8, ( )

671  is the 224th term of the given series

Step-by-step explanation:

The given sequence is

2,5,8,11....

First term that is 2

common difference that is 3

we have to find 224th term

That is n =224

using

On solving the above equation we get

Hence, 224th term of the given series is 671

Function rule for the arithmetic sequence is;

The 224th term of the arithmetic sequence  is: 671

Step-by-step explanation:

Arithmetic sequence: A sequence of number which increases or decreases by a constant amount each term.

Formula for nth term of arithmetic sequence is:

where a is the first term in the sequence, d is the common difference and n is the number of terms;

Given an arithmetic sequence:

2, 5 , 8, 11, ......

First term(a) = 2

Common difference(d) = 3 (Because the difference between the two consecutive terms is 3) i,e

5-2 = 3

8-5 = 3

11 -8 =3 ans so on,....

To find the 224th term;

we have,

a = 2 , d = 3 and n = 224

Using formula for nth arithmetic sequence;

=671

therefore, the 224th term for the given arithmetic sequence is, 671

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
