A baby kangaroo is grazing in a paddock 20 metres outside the National Park. He sees a ute full of noisy teenagers driving his way, and decides that the park might be safer than a farmers paddock. He bounds toward the fence, his first leap taking him 5 metres. Each successive leap is 20% less than the previous leap. How many leaps will it take the kangaroo to reach safety?
Explanation
The baby kangaroo takes a 5-meter leap initially. Each subsequent leap is 20% less than the previous leap. This means that the length of each leap can be calculated by multiplying the previous leap by 0.8.
So, the lengths of the leaps would be:
1st leap: 5 meters
2nd leap: 5 * 0.8 = 4 meters
3rd leap: 4 * 0.8 = 3.2 meters
4th leap: 3.2 * 0.8 = 2.56 meters
5th leap: 2.56 * 0.8 = 2.048 meters
6th leap: 2.048 * 0.8 = 1.6384 meters
7th leap: 1.6384 * 0.8 = 1.31072 meters
8th leap: 1.31072 * 0.8 = 1.048576 meters
Therefore, it will take the kangaroo 8 leaps to reach safety.Rate this question:

I spill a 20 litre can of paint on the carpet. I’m in serious trouble. When it starts, it covers 200 square centimetres. In the first minute it has spread by 40 square centimetres, and is growing by 20% each minute. What is the final area of the stain in square centimetres?
Explanation
Use ar to find the sequence. If it is growing by 20%, the value for r will be 0.2. Find the value for the infinite series. Add to original coverage.Rate this question:

Correct Answer
A. No, it is geometric but it divergesExplanation
A geometric series can only be calculated if the common ratio between consecutive terms is between -1 and 1. In this case, since it is mentioned that the sequence is diverging, it means that the terms are not approaching a specific value and therefore the common ratio is not within the acceptable range. Hence, an infinite geometric series cannot be calculated from this sequence.Rate this question:

Correct Answer
A. No, it is geometric but it divergesExplanation
The given sequence is geometric because each term is obtained by multiplying the previous term by a common ratio. However, it diverges because the common ratio is greater than 1, causing the terms to increase without bound. In an infinite geometric series, the terms must approach zero for the series to converge. Since this sequence does not meet that condition, it cannot be used to calculate an infinite geometric series.Rate this question:
