Answer:
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 missingterms 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 SeriesWe 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.How to Find The Missing Number in A Series?In the given missing number series, you can sometimes find missing numbers at the beginning or at the end of the series. The layout in the missing number series is similar to the wrong number series, you have to identify the rule and then use the rule to estimate the next number.Here Are The Steps To Find The Missing Numbers In A Series1. Select 2 or 3 terms to the text which rule will be applied to find the missing number. For example: If you have 5 numbers in a series then pick the first 3 terms to check the rule that is to be applied.2. While choosing the number to check the rule, select the number that is easy to operate. These include terms that are factors of 2, 3, 5, or 10. Check the series with some common methods such as the sum of the terms, squares, cube, or other.Let Us Understand Through An Example:Missing Number Series QuestionFind 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 120How To Find A Missing Number In a Sequence?Here are the steps to find missing numbers in sequence:1. Identity, if the order of number given is ascending ( smaller to larger number) or descending ( larger to smaller number)2. Calculate the differences between those that are next to each other.3. Estimate the difference between numbers to calculate the missing number.Let us Understand The Above Steps Through An Example:Find The Missing Number in the Following Sequence 30, 23? 9.Solution: The numbers given in sequence are in decreasing order. It implies that numbers are arranged from larger to smaller.The difference between the numbers 30-23=7As the sequence of the numbers is in decreasing order, subtract 7 from 23. The missing number is 16 as it is 7 more than the previous number 9.
Answer:
Volume of one cone=38.5 cm
3
Number of cones formed n=n=126
Hence the solid sphere can be melted in 126 smaller cones .
