Answer:
1. My arithmetic sequence:
3, 5 , 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31
2. Sequence:
Just add 2 every number. For example: 3+2 = 5, 5+2= 7, 7+2=9 and so forth.
3. Equation:
a{n}=a{1}+(n-1)d
a{1}=3+(2-1)2
a{1}= 5 (2nd term ) and so on...
4. Sum of the first 15 terms.
3 + 5+ 7 + 9 +11 + 13 +15 +17 +19+ 21 +23 +25 +27 +29+ 31 = 255
