using visual studio, please tell me the correct code

to get this outcome

Part A: (Displaying Triangles) Write an app called Triangles that displays the following patterns separately, one below the other. Use for loops to generate the patterns. All asterisks (*) should be displayed by a single statement of the form Console.Write("*'); which causes the asterisks to display side by side. A statement of the form Console. Writeline(); can be used to move to the next line. A statement of the form Console. Write(' '); can be used to display a space for the last two patterns. There should be no other output statements in the app. [Hint: The last two patterns require that each line begin with an appropriate number of blank spaces.] Part B: (Calculating the Value of ) Write a program called FindPi that calculates the value of from the infinite series: =434+5474+94114+ The program prompts a message for a user to enter the number of terms, and then display a table that shows the value of r approximated by computing one term of this series, by two terms, by three terms, and so on.
