Show activity on this post. The tenth term of a sequence is T 10 T 10. The general term is often expressed as the nth n th term and is written as T n T n.

We can commonly represent sequences as x 1 x 2x 3x n where 123 are the positions of the numbers and n is the nth term. Natalia is writing a recursive formula to represent the sequence. An 1 21 2n1 a n 1 2 1 2 n - 1.

When writing an explicit formula to represent the amount of beach remaining each year which value should she use as the common ratio. Lena is asked to write an explicit formula for the graphed geometric sequence. Here a1 12.

Multiply 1 2 1 2 by 1 2n1 1 2 n - 1. The sequence should be geometric which means the first term 12 and the common ratio is 25. The order is important.

0989 Sebastian writes the recursive formula fx1 4fx to represent a geometric sequence whose second term is 12. Number of games minimum turns to win 1. Which describes the translation of fx to gx.

Substitute each value of n n into the formula. Begin with n 1 n 1 to find the first term a1 a 1. Repeat with values 2 through 5 for n n.

To find the formula for the nth term we need a 1 and d. In mathematics we use the word sequence to refer to an ordered set of numbers ie a set of numbers that occur one after the other. F x1 2f x A sequence of numbers begins with 12 and progresses geometrically.

Recall the slope-intercept form of a line is y mxb y m x b. The formula that could be used for showing the sequence is option A. When writing an explicit formula to represent the amount of beach remaining each year which value.

Learn more about the sequence here. We commonly refer to a set of events that occur one after the other as a sequence of events. Given n N I need to get just enough more than half of it.

Which explicit formula can be used to. Write the first five terms of the sequence defined by the explicit formula an 3n8 a n 3 n 8. Mathematics 21062019 1740.

A conservationist determines that a particular beach is eroding at a rate of 11 each year. Whereas series is defined as the sum of sequences which means that if we add up the numbers of the sequence then we get a series. To describe terms in a number pattern we use the following notation.

Now The explicit formula should be. The general formula that represents the given sequence is. To find the second term a2 a 2 use n 2 n 2.

The sequence T_n_n ge 1 has closed formula T_n fracnn12text 1 2 4 8 16 32ldots The powers of 2. C-2 23 -5 13 -10 23 -21 13 -42 23 Which formula can be used to describe the sequence. For example you can think this is.

The graph shows fx 12x and its translation gx. The first term of a sequence is T 1 T 1. The complete question is-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. Fx 1225x 1 fx 2512x 1 fx 1225x fx 2512x.

C-2 23 -5 13 -10 23 -21 13 -42 23 Which formula can be used to describe the sequence. And r 25 So the formula is. For instance the numbers 2 4 6 8 form a sequence.
