Can a Common Difference of an Arithmetic Series Be Found by Subtracting Any Term From the Previous Term?
When the common difference of an arithmetic sequence is negative, then the terms of the arithmetic sequence are decreasing?
What is the difference between the sum of the first 20 terms of the arithmetic sequence 6 10 14 and 15 19 23?
What is the common difference of the arithmetic sequence in which the 18th term minus the 14th term is 32?
