Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
Question
The analysis of accidents which happen per year is the average of the number of accidents which occurred in the 2 previous years
a)Calculate a recurrence relation for {An} where An is the number of accidents which happened in year x using the information given in the question above
b)Considering that three hundred thousand accidents occurred in year two and hundred thousand accidents occurred in year one, calculate the value for An
Note: Both questions asked are different.Kindly read carefully
Recurrence relations: An equation that allow us to compute the term of a sequence from preceding terms.
Part (a)
Let be the number of accidents happened in year x named as and , are the number of accidents that happened in two preceding two years.
Then according to question,
Therefore, the recurrence relation is .
