Prove the following statement is true by using mathematical induction. 2+ 4+ 6+ ... + 2n = n(n + 1)
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Steps to perform Mathematical Induction:
1) Consider an initial value (say n = 1) for which the statement is true, then show that the statement is true for n = initial value.
2) Assume the statement is true for any value of n = k.
3) Then prove the statement is true for n = k+1. By breaking n = k+1 into two parts, one part is n = k (which is already proved) and try to prove the other part.
The given statement is .
The main objective is to prove that for every , the given statement is true.
This can be proved by mathematical induction.
