 Follow the daily SSC CHSL CGL and bank exams important concepts, where examdays team updating daily based article concepts, today we are going to discuss on Number Series important concepts along with tips and tricks information.

Number Series a concept, where the expectation of skills are implemented with the analytical and critical thinking process. any candidate has to expect the next upcoming value of the number with own/available methodologies.

For Example:

• If a candidate has Number 1, 3, 5, 7, ?, …soon, then a candidate easily states that next number as per odd rule of mathematics and also same passed in even rule also, like 2, 4, 6 ,8 10.
• Candidate should aware of mathematical calculations by building own mathematical formulas or equations, whenever it applies by using basic functions of maths like, (a+b)^2 = a^2+b^2+2ab (fundamemtal equations)

Examples of Number Series:

1. Series: 5, 11, 6, 12, 7, 13, … What number should come next?

Explanation: This is a simple alternating addition and subtraction series.

2. Series: 21, 20, 24, 23, 25, 24, … What number should come next?

3. 1, 9, 125, 49, 729, 121, 2147

A. 2147

B. 729

C. 125

D. 1

4. 1 2 12 63 316 ?

Solution:

1 * 1 + 13 = 2

2 * 2 + 23 = 12

12 * 3 + 33 = 63

63 * 4 + 43 = 316

316 * 5 + 53 = 1705

5. 8,12,24,46,72,108,152
