Q. What is the next term of the arithmetic sequence?−4,−9,−14,−19
Identify sequence type: Identify the type of sequence.The sequence −4, −9, −14, −19 has a constant difference between its terms, which indicates that it is an arithmetic sequence.
Determine common difference: Determine the common difference of the sequence.To find the common difference, subtract the first term from the second term: −9−(−4)=−5.
Verify common difference: Verify the common difference with another pair of consecutive terms.Subtract the third term from the fourth term: −19−(−14)=−5. This confirms that the common difference is indeed −5.
Calculate next term: Calculate the next term in the sequence.To find the next term, add the common difference to the last given term: −19+(−5)=−24.
