Give the first six terms of the following sequences. You can assume that the sequences start with an index of 1 a) A geometric sequence in which the first value is 5 and the common ratio is 8. [3 points] b) An arithmetic sequence in which the first value is 34 and the common difference is 5. [3 points] c)  Evaluate the summation [4 points]        ∑200k=0 (2 + 4k)

a) A locker combination is made up of five digits using only the digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. The combination must start with an even digit, follow the pattern even-odd-even-odd-even, and all digits must be distinct. How many such combinations are possible?

(10 points)   a) How many ways can Susan plan her schedule if there are no restrictions on the number of days she studies each of the four subjects? [5 points]   b) How many ways can Susan plan her schedule if she decides that the number of days she studies each subject will be the same? [5 points]

A tree farmer plants five new trees on his farm at the end of each month. Let an​ denote the total number of trees he has after n months. Initially, he has a0=50 trees. a) What is a10​? [4 Points]   b) If the farmer spends $3 per month to maintain each tree, what is the total maintenance cost he has paid after 1 year (12 months)? Provide the closed-form mathematical expression for this amount (do not calculate the actual value).(Assume that he starts maintaining trees at the beginning of each month and includes all existing trees for that month.)
