Mathematical Induction
is a process uses in College Algebra
It can be used to prove
that a sequence is equal to an equation
For Example:
1+3+5+7+n+2=2n+1
there are 3 steps to mathematical induction
the first includes proving that the equation is true for n=1
the second includes substituting k for every n-term
the third involves substituting k+1 for every k-term to prove that both sides are equal
Assume something (e.g. equations) using k then prove k+1 using k.
Step 1: Formulate the statement to be proven by induction. Step 2: Show that there is at least one value of the natural numbers, n, for which the statement is true. Step 3: Show that, if you assume it is true for any natural number m, greater or equal to n, then it must be true for the next value, m+1. Then, by induction, you have proven that the statement (step 1) is true for all natural numbers greater than or equal to n. Note that n need not be 1.

False
"Mathematical induction" is a misleading name. Ordinarily, "induction" means observing that something is true in all known examples and concluding that it is always true. A famous example is "all swans are white", which was believed true for a long time. Eventually black swans were discovered in Australia. Mathematical induction is quite different. The principle of mathematical induction says that: * if some statement S(n) about a number is true for the number 1, and * the conditional statement S(k) true implies S(k+1) true, for each k then S(n) is true for all n. (You can start with 0 instead of 1 if appropriate.) This principle is a theorem of set theory. It can be used in deduction like any other theorem. The principle of definition by mathematical induction (as in the definition of the factorial function) is also a theorem of set theory. Although it is true that mathematical induction is a theorem of set theory, it is more true in spirit to say that it is built into the foundations of mathematics as a fundamental deductive principle. In set theory the Axiom of Infinity essentially contains the principle of mathematical induction. My reference for set theory as a foundation for mathematics is the classic text "Naive Set Theory" by Paul Halmos. Warning: This is an advanced book, despite the title. Set theory at this level really only makes sense after several years of college/university mathematics study.
Euclid in 300 BCE, but possibly Plato in 370 BCE. See related link.

Mathematical induction is just a way of proving a statement to be true for all positive integers: prove the statement to be true about 1; then assume it to be true for a generic integer x, and prove it to be true for x + 1; it therefore must be true for all positive integers.
use mathematicl induction to show that (5/4/4n+1)powerox1/2< or equal(1.3.5....(2n+1)/2.4.6.....(2n)< or equal(3/4/2n+1)power of 1/2

It's not. If n = 2, then 3n - 1 = 3*2 - 1 = 6 - 1 = 5, which isn't divisible by 2.
Yes the Induction motor works on Electromagnetic induction principle.
