Example Question #1 :How To Find The Next Term In An Arithmetic Sequence
Each term in the sequence is one less than twice the previous term.
So,
Example Question #2 :How To Find The Next Term In An Arithmetic Sequence
What is the next number in the following series: 0, 3, 8, 15, 24 . . . ?
41
35
40
37
32
35
The series is defined by n2– 1 starting at n = 1. The sixth number in the series then equal to 62– 1 = 35.
Example Question #1 :How To Find The Next Term In An Arithmetic Sequence
A sequence of numbers is as follows:
What is the sum of the first seven numbers in the sequence?
490
248
719
621
1529
621
The pattern of the sequence is (x+1) * 2.
We have the first 5 terms, so we need terms 6 and 7:
(78+1) * 2 = 158
(158+1) * 2 = 318
3 + 8 + 18 +38 + 78 + 158 + 318 = 621
Example Question #4 :How To Find The Next Term In An Arithmetic Sequence
Find the next term of the following sequence:
More information is needed
The sequence provided is arithmetic. An arithmetic sequence has a common difference between each consecutive term. In this case, the difference is
You can also use a formula to find the next term of an arithmetic sequence:
where
Example Question #5 :How To Find The Next Term In An Arithmetic Sequence
Solve each problem and decide which is the best of the choices given.
Find the sixth term in the following arithmetic sequence.
First find the common difference of the sequence,
Thus there is a common difference of
so follow that pattern for another
Example Question #6 :How To Find The Next Term In An Arithmetic Sequence
Find the missing number in the sequence:

For the fourth term,
Example Question #7 :How To Find The Next Term In An Arithmetic Sequence
An arithmetic sequence begins as follows:
Express the next term of the sequence in simplest radical form.
利用自由基原理的产物e, we can simplify the first two terms of the sequence as follows:

Add this to the second term to obtain the desired third term:
Example Question #8 :How To Find The Next Term In An Arithmetic Sequence
An arithmetic sequence begins as follows:
Give the next term of the sequence in simplest radical form.
None of the other choices gives the correct response.
None of the other choices gives the correct response.
Since no perfect square integer greater than 1 divides evenly into 5 or 10, both of the first two terms of the sequence are in simplest form.
