Introduction

In mathematics, identifying patterns and relationships between numbers is a fundamental concept that has numerous applications in various fields. The given table represents a sequence of term values, where each term is associated with a unique number. Our objective is to analyze this sequence, identify any patterns, and determine the value of the missing term.

Analyzing the Sequence

At first glance, the sequence appears to be a simple arithmetic progression, where each term increases by a fixed constant. However, upon closer inspection, we notice that the differences between consecutive terms are not constant. To better understand the pattern, let's examine the differences between consecutive terms:

Term Number	Term Value	Difference
1	4	-
2	7	3
3	10	3
4	13	3
5	16	3
10	-	-

As we can see, the differences between consecutive terms are constant, with a value of 3. This suggests that the sequence is indeed an arithmetic progression with a common difference of 3.

Determining the Missing Term

Now that we have identified the pattern, we can use it to determine the value of the missing term. Since the sequence is an arithmetic progression with a common difference of 3, we can use the formula for the nth term of an arithmetic progression:

an = a1 + (n - 1)d

where an is the nth term, a1 is the first term, n is the term number, and d is the common difference.

In this case, we know that the first term (a1) is 4, the common difference (d) is 3, and we want to find the 10th term (an). Plugging in these values, we get:

a10 = 4 + (10 - 1)3 a10 = 4 + 9(3) a10 = 4 + 27 a10 = 31

Therefore, the value of the missing term is 31.

Conclusion

In conclusion, our analysis of the given sequence has revealed a pattern of an arithmetic progression with a common difference of 3. By using this pattern, we were able to determine the value of the missing term, which is 31. This example illustrates the importance of identifying patterns and relationships in mathematics, as it allows us to make predictions and solve problems.

Conclusion

Q: What is an arithmetic progression?

A: An arithmetic progression is a sequence of numbers in which the difference between any two consecutive terms is constant. In other words, if we have a sequence of numbers a1, a2, a3, ..., an, then the difference between any two consecutive terms is the same, i.e., a2 - a1 = a3 - a2 = ... = an - an-1.

Q: How do I determine the common difference of an arithmetic progression?

A: To determine the common difference of an arithmetic progression, we can use the formula:

d = (an - a1) / (n - 1)

where d is the common difference, an is the nth term, a1 is the first term, and n is the number of terms.

Q: How do I determine the nth term of an arithmetic progression?

A: To determine the nth term of an arithmetic progression, we can use the formula:

an = a1 + (n - 1)d

where an is the nth term, a1 is the first term, n is the term number, and d is the common difference.
