2.3 D figure made of all triangles.That figure is called triangular pyramid.

2-Triangular pyramid

3.3 D figure with six congruent squares is called cube.

3-cube

4.3 D figure with two triangle bases and rectangles for the rest of its faces.That figure is called triangular prism.

4-Triangular prism

5.3 D figure with circular bases is called cylinder.

5-Cylinder

6.3 D figure with a rectangle as a base and triangle for the rest of its bases.

That figure is called rectangular pyramid.

6-Rectangular pyramid

7.3 D figure with one circular base and one vertex.That figure is called cone.

Find the nth term of the sequence:<br>23, 19, 13, 5, -5.......<br>​
Maurinko [17]

Answer:

Step-by-step explanation:

Given the sequence :

23, 19, 13, 5, -5.......

From the sequence, the common difference is unequal, as their is a constant Increment in the difference after successive numbers.

19 - 23 = -4

13 - 19 = -6

5 - 13 = -8

-5 - 5= -10

Hence an constant difference of - 2 after each successive difference.

Hence, this is a quadratic sequence

With the formula

an² + bn + c
