Full solution

Q. What is the next term of the arithmetic sequence?\newline7,11,15,197, 11, 15, 19
  1. Identify sequence type: Identify the type of sequence.\newlineThe sequence 7,11,15,197, 11, 15, 19 appears to have a constant difference between consecutive terms, which suggests it is an arithmetic sequence.
  2. Determine common difference: Determine the common difference in the arithmetic sequence.\newlineTo find the common difference, subtract the first term from the second term: 117=411 - 7 = 4.
  3. Verify common difference: Verify the common difference by checking other consecutive terms.\newlineSubtract the second term from the third term: 1511=415 - 11 = 4, and the third term from the fourth term: 1915=419 - 15 = 4. The common difference is consistent.
  4. Calculate next term: Calculate the next term in the sequence by adding the common difference to the last given term.\newlineThe last term given is 1919, so add the common difference of 44 to find the next term: 19+4=2319 + 4 = 23.
