If the sequence continues with the same be the tenth term of the sequence? Show your work. 9. 10. n n 48 0 4 0 10 75 2 108 2 16 3 22 3 147 4 28 4 192 5 34 5 24311. Represent the series for the sum of the first 25 positive integers and for the sum of the squares of the first 25 positive integers using sigma notation. Then use the formulas m [k = n(n+ 1) and k2 _ n(n + 1)(2n + 1) 2 6 to find the sums. k = 1 k = 1
