Q. What is the next term of the arithmetic sequence?7,5,3,
Identify sequence type: Identify the type of sequence.The sequence 7,5,3 appears to have a constant difference between terms, which suggests it is an arithmetic sequence.
Determine common difference: Determine the common difference in the arithmetic sequence.The difference between the first two terms is 5−7=−2.The difference between the second and third terms is 3−5=−2.The common difference is −2.
Calculate next term: Calculate the next term in the sequence.To find the next term, add the common difference to the last known term.The last known term is 3, so the next term is 3+(−2)=1.
