MRSAFPI MATHS QUESTION MISSING NUMBER SERIES
Missing numbers are the numbers that have been missed in the given series of a number with similar differences among them. The method of writing the missing numbers is stated as finding similar changes between those numbers and filling the missing terms in the specific series and places. In this article we will learn what are missing numbers, missing number series, how to find missing numbers in the series and sequence with examples, solved examples on missing numbers in the series and sequence, etc.
Missing number series is a series where one term is left for the aspirant to understand the pattern and find out the missing number using mathematical operations. A better approach to solve these questions is to identify the pattern or the formula used to create the series.
We have seen that number series is a collection of numbers that follows a particular rule or formula. There are various types of series and missing number series is one among them. In missing number series, a series is given with one missing number and you are asked to find the missing term. To find the missing number, we first identify the rule or formula which is applied in the given missing number series. Let us learn the method to find the missing number in a series
Find the missing number 1, 2 6, 24,?
Solution: The given sequence has 4 terms. We will check which rule is applied by picking the first 3 terms. The second number in the sequence is 2 and the first number is 1 which means 1 is either added or 2 has been multiplied to obtain the second term. The third term is 6 which we got from 2 by multiplying with 3. Hence, now we have 1 x 1, 1 x 2, 2 x 3, and 6 x 4. Thus, we have identified the rule and accordingly, the last term will be 24 x 5= 120.
Hence, the missing number is 120
- Before solving questions always observe the flow of series whether it is increasing order or in decreasing order.
- If there is gradual increase in series , then it has highly chances of addition.
- If there is gradual decrease in series, then it has highly chances of subtraction
- If there is huge increase in series then probably there would be multiplication or along with it addition and subtraction or square and cube.
- If there is huge decrease in series then probably there would be division or along with it addition and subtraction or square and cube
- Memorise square from 1 to 50 and cubes from 1 to 13.
- One should good with tables as they can help a lot while solving questions.
