The first term of the sequence is 4.
To find the second term, add 15 to the first term:
[tex]4+15=19[/tex]
Next, subtract 10 from the second term to get the third term:
[tex]19-10=9[/tex]
Continue to add 15 and subtract 10 to get the first twelve numbers as follows:
[tex]4,19,9,24,14,29,19,34,24,39,29,44[/tex]
