Full solution

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