The Sum of First 100 Even Natural Number is

The problem states that the sum of first 100 even natural number is 10100.

Let's check how

Algorithm used

The sum of first 100 even number

2+4+6+8+10+12-----+200

1st term = 2, last term = 200, n=100

100/2(2+200) = 50 x 202

Answer = 10100.

How to Solve Math Problems?

Check the following methods

1. Understand the Problem

  • Algebra (for equations)
  • Geometry (for shapes, areas, volumes)
  • Arithmetic (for basic calculations)
  • Word problems (for applying math to real-world situations)
• Break down complex problems: If the problem seems complicated, break it into smaller, manageable parts.

3. Translate the Problem into Mathematical Form

• For equations: Write any equations or expressions that represent the situation.
• For word problems: Identify variables for unknown quantities, translate the problem into an equation or set of equations.
• For geometry problems: Draw diagrams to help visualize the problem.

4. Solve the Problem

• Follow through with the chosen method:
  • Algebra: Solve equations step by step, isolate the variable.
  • Geometry: Use formulas for areas, volumes, perimeters, etc.
  • Word problems: Apply the correct mathematical operations to the situation (addition, subtraction, multiplication, division).
• Simplify where necessary: Simplify the expression or solve the equation.

5. Check Your Work

• Substitute the solution back: If possible, substitute your answer back into the original problem to verify it satisfies all conditions.
• Review calculations: Double-check for any mathematical mistakes.

6. Write the Final Answer
