I need help. Please show the step by step solution so that i could follow along. Thank you.

4, 9, 14, 19, ...... A. Determine if the sequence is arithmetic, geometric, or neither. B. Find the explicit formula, also know as the "general rule", an for the sequence. Your explicit formula should generate the sequence given in your problem when you plug in the positive integers 1,2,3,4.... for n. C. Use your explicit formula to find the 10th term a10. A. Find the explicit formula for the sequence. Use the explicit formula to find the term that is requested in the problem. B. Use summation notation to write the sum of some number of terms. This is an exercise in using the summation notation properly. No calculations are needed here; it is just practice in using the mathematical notation for sums. C. Find the requested sum. Use one of the formulas for either the sun of a geometric sequence or sum of an arithmetic sequence, or the sum of an infinite number of terms of a geometric sequence. 5, 11, 17, 23, 29, ...... A. Find the thousandth term, a1000. B. Use summation notation to write the sum of the first thousand terms. C. Use the Sum of Arithmetic or Geometric Sequences formulas to find S1000, the sum of the first 1000 terms
