# Prime number and mark questions So, 46 is the wrong number in this particular series. Asked by: Rob Davis Answer It's certainly not immediately obvious why it is important to find the next highest prime number. However, those numbers must have the property that they are composed of exactly 2 primes so to make a big number we need big primes. Yet the absurd idea of taking the square root of a negative number has led to a branch of mathematics that is insanely useful in physics and electrical engineering, and directly applicable to real world problems.

It can be seen that before the question mark, ten has been added, so the next addition would be twelve. Any book on cryptography can provide you with more details.

Nobody knows for sure, though, that there isn't a quick, easy way of factoring numbers Most Popular Articles. So you have got the right clue. I have often read that scientists are searching for the next prime number. Sol: In this case consecutive odd numbers have been added in the increasing order.

### Mcq on prime numbers

Thus 47 is the wrong number in this particular series. So there is no specific logic. I can almost guarantee that there isn't some huge equation that will solve all our problems if we just find one larger prime than we know now. Firstly one, then three, then five and nine. Nobody knows for sure, though, that there isn't a quick, easy way of factoring numbers The next number, as is clear from the above illustration, is obtained by multiplying the last number by 6. My question is why? To make stronger crypting algorithms, we need bigger numbers that are the basis for making keys. Asked by: Rob Davis Answer It's certainly not immediately obvious why it is important to find the next highest prime number. Answered by: Alf Salte, M. I would guess and this is pure speculation that the study of prime numbers in general would help us to figure out whether the encryption systems we use today are as secure as we think they are. I would argue that the first person to suggest the imaginary number 'i' which is the square root of negative one was probably asked a similar if not much more derisive question. So, 46 is the wrong number in this particular series.

In order to get the next number after 34, 6 would be added to it. Example 7: What should come in place of question mark in the following series: 2, 3, 6, 11, 18, 27,?

## Prime numbers problems and solutions

Contact Us. In order to get the next number after 34, 6 would be added to it. What use is it? Essentially crypting a message using popular crypting algorithms require you to know 2 large primes. Nobody knows for sure, though, that there isn't a quick, easy way of factoring numbers Most Popular Articles. The next number, as is clear from the above illustration, is obtained by multiplying the last number by 6. Example 6: What should come in place of question mark in the following series; 16, 22, 28, 34,? Thus 47 is the wrong number in this particular series. Sol: In this case consecutive odd numbers have been added in the increasing order. I can almost guarantee that there isn't some huge equation that will solve all our problems if we just find one larger prime than we know now. I have often read that scientists are searching for the next prime number. First of all, the mathematics regarding prime numbers is very powerful. The value of searching for the next highest prime number lies mainly in the search. How can knowing the next highest prime number be of any benefit?

I would guess and this is pure speculation that the study of prime numbers in general would help us to figure out whether the encryption systems we use today are as secure as we think they are.
