Q. What is the next term of the arithmetic sequence?−7,−3,1,5,9
Identify sequence type: Identify the type of sequence.The sequence −7, −3, 1, 5, 9 appears to have a constant difference between consecutive terms, which suggests it is an arithmetic sequence.
Determine common difference: Determine the common difference in the arithmetic sequence.To find the common difference, subtract any term from the term that follows it. For example, −3−(−7)=4.
Verify common difference: Verify the common difference by checking it with another pair of consecutive terms.Let's check the difference between 1 and 5: 5−1=4. The common difference is confirmed to be 4.
Calculate next term: Calculate the next term in the sequence by adding the common difference to the last known term.The last known term is 9, so adding the common difference of 4 gives us 9+4=13.
