Q. What is the next term of the arithmetic sequence?7,11,15,19
Identify sequence type: Identify the type of sequence.The sequence 7,11,15,19 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 the first term from the second term: 11−7=4.
Verify common difference: Verify the common difference by checking other consecutive terms.Subtract the second term from the third term: 15−11=4, and the third term from the fourth term: 19−15=4. The common difference is consistent.
Calculate next term: Calculate the next term in the sequence by adding the common difference to the last given term.The last term given is 19, so add the common difference of 4 to find the next term: 19+4=23.
