## What are the number series practice questions?

In the Number Series Practice Questions, you will see many questions that are based on the concepts that we already learned. So let us begin and remember to set a time limit for yourself before you attempt this section. Here we deal with the questions in which series of numbers, which are generally called the terms of the series is given.

## How do you know if a series is a number series?

The best way of approaching number series questions is to observe the difference between various terms. If we see a constant difference, then it’s a constant difference series. If the difference is decreasing or increasing by a constant number , then it is a series of type 2 or type 3.

**Do you need any other resources to study number series?**

You never will need any other resource to study. There are the following most popular number series, We will discuss all these in details here we are just introducing them to you, so don’t worry if you don’t see the pattern just yet, after this post you will be able solve any Number Series Question in the world .

**What is numbernumber series in Bank Exams?**

Number series is one of the most common topics from the Quantitative aptitude section from which questions are asked in the various Bank exams. There are three mains bank exams which are conducted in the country.

### How do you find 22 with the difference 6 to 16?

Let us try to use this theory in a question. 1,2,4,7,11,16,? We can clearly observe that the series is increasing with the difference : +1, +2, +3 ,+4 , +5. So, we will obtain our number by adding 6 to 16 which gives us 22.

### What is the 7th term of the original series?

The 2nd , 4th and 7th term make a series of 10 , 11 , 12… . So, our answer will be 9 which is the 7th term of the original series. 6. Miscellaneous series Some series do not come under any of the above mentioned categories but are very important and also asked in many examinations.

**What are the terms of the series?**

Here we deal with the questions in which series of numbers, which are generally called the terms of the series is given. These terms follow a certain pattern throughout the series. Candidates are asked either to find a missing number or to find the one that does not follow the pattern of the series.

**How do you form a number series?**

A number series can be formed by using various characteristics of numbers and by using various types of calculations. Here we will see how to find a missing term when we are given a sequence of numbers including one or more missing numbers.

#### Is N=55/9 a whole number?

If we use two digit numbers, then we’ll have whole numbers N (tens) and M (units) where N*10+M=100 and N+M=45. It follows that N*9=55; Therefore N=55/9, which is not a whole number. (From Polya) Heuristic: If an answer doesn’t present itself, think about proving the problem cannot be solved.

#### What is the next number in the sequence 1 2 3 4?

Step by step solution of the sequence is Series are based on square of a number 1 = 12, 4 = 22, 9 = 32, 16 = 42, 25 = 52 ∴ The next number for given series 1, 2, 3, 4, 5 is 6 ∴ Next possible number is 62 = 36

**How do you find the Mersenne numbers of prime numbers?**

M n ≐ 2 n − 1 = ∑ k = 0 n − 1 2 k. These numbers M n are called the Mersenne numbers. The sequence continues M 6 = 2 6 − 1 = 63, M 7 = 2 7 − 1 = 127, etc. An interesting fact about Mersenne numbers is that for M n to be prime, n must be prime. Not all primes n work though: for example 11 is prime, but M 11 = 2 11 − 1 = 2047 = 23 ⋅ 89 is not prime.

**What are the numbers in the alternating subtraction and addition series?**

In this simple alternating subtraction and addition series; 1 is subtracted, then 2 is added, and so on. Look at this series: 53, 53, 40, 40, 27, 27, What number should come next? In this series, each number is repeated, then 13 is subtracted to arrive at the next number.
