Which formula can be used to find the nth term of the geometric sequence below.

. A series can be highly generalized as the sum of all the terms in a sequence. Then a recursive formula for this sequence will be needed to compute all the previous terms and find the value of t n. An arithmetic progression is one of the common examples of sequence and series.

C-2 23 -5 13 -10 23 -21 13 -42 23 Which formula can be used to describe the sequence. Given an explicit formula write the first n n terms of a sequence. Examples of Arithmetic Sequence Explicit formula.

A student wrote the first three values in a geometric sequence as shown below. Substitute each value of n n into the formula. Thanks for the A2A.

Geometric Mean is the average of two numbers in a geometric sequence. A₁ -81 a₂ 108 a₃ -144 and a₄ -144 find the common ratio of the given geometric sequence by using r. Find the explicit formula of the sequence 3 7 11 15 19.

Then I solved to find a1 45. However there has to be a definite relationship between all the terms of the sequence. Which formula can be used to describe the sequence-3 35 -325 3125 -3625.

This formula can also be defined as Arithmetic Sequence Recursive Formula. If t 1 t 2 t 3 t n is a set of series or a sequence. The common difference d can be found by subtracting the first term from the second term which in this problem yields 4.

Answer 1 of 37. The formula which can be used to describe the sequence -81 108 -144 192is a_n a₁ -43ⁿ¹. Explain how you arrived at your answer.

Continue in the same manner until you have identified all n n terms. First I substituted 1215 for an 4 for n and 3 for r in the general form. Your teacher to keep the class busy tells everyone to sum the numbers 1.

Arithmetic mean for an arithmetic sequence can be calculated using the below formula. In short a sequence is a list of itemsobjects which have been arranged in a sequential way. A bouncing toy reaches a height of 64 inches at its first peak 48 inches at.

To find the second term a2 a 2 use n 2 n 2. As you can observe from the sequence itself it is an arithmetic sequence which includes the first term followed by other. Find the explicit formula of the sequence 3 -2 -7.

To find a given term substitute the corresponding value of n into the nth term formula. T n t n-1. -23 4 24 144.

3 10 2 32 and so the tenth term of the sequence is 32. For example if the nth term is 3n 2 the 10th term of the sequence can be found by substituting n 10 into the nth term. Suppose a term of a geometric sequence is a4 1215 and the common ratio is 3.

The nth term is a formula used to generate any term of a sequence. Which of the following shows the correct relationship between these terms. Begin with n 1 n 1 to find the first term a1 a 1.

A nm2. A conservationist determines that a particular beach is eroding at a rate of 11 each year. Write the formula for this sequence in the form an a1 rn1.

Arithmetic Mean can be used to calculate the central tendency or the approximate centre point of an arithmetic sequence. Ill answer this question with a story. When writing an explicit formula to represent the amount of beach remaining each year which value.

Which formula can be used to describe the sequence. Fiona wrote the sequence below.
