N and N + 1
The sum of the nth term and the (n + 1)th term of an arithmetic sequence is 62. The sum of the first and second terms is 14. The sum of the third and fourth terms is 22. Find n.
SolutionIn order to make it feasible for teachers to use these problems in their classwork, no solutions are publicly visible, so students cannot simply look up the answers. If you would like to view the solutions to these problems, you must have a Virtual Classroom subscription.
In an arithmetic sequence, the first term is twice the fourth term, and the second term is equal to 9 more than the sum of the fifth and sixth terms.
What is the seventh term of the sequence?
The sum of the first three terms of an arithmetic sequence is 72. The sum of the next three terms is 189. What is the sum of the next three terms after that?
The sum of the squares of the first two terms in an arithemetic sequence is 52. The common difference is 2. What are the possible values for the first term?
The common difference in an arithmetic sequence is two more than the first term. The fourth term is 30. What is the first term?
If you add the first five even numbered terms of an arithmetic sequence, the result is 27 more than if we had added the first five odd numbered terms. What is the common difference of the sequence?
