N-3, n-2, n-1, n  and the sum is

4n-6=198  add 6 to both sides

4n=204  divide both sides by 4

n=51

So the fourth number is 51.

Write a word problem that involves combining three equal groups
ipn [44]
Combining three equal groups means that we will mainly depend on multiplying the quantity by 3 to get the total

<u><em>Examples are shown below:</em></u>
1- Mrs Nadia teaches three classes. Each class has 25 student. How many students does Mrs Nadia teach in total?
<u>In this problem</u> we will be combining three equal groups of students where each group has 25 students, therefore:
Total number of students = 3 * 25 = 75 students

2- John has three bags of candies. Each bag contains 10 pieces of candies. How many candies does John has?
<u>In this problem</u> we will be combining three equal groups of candies where each group has 10 pieces, therefore:
Total number of candies = 3 * 10 = 30 candies

Hope this helps :)
