Problem

The series 4, plus, 6, plus, 9 can be written using sigma notation (also called summation notation):
sum, start subscript, k, equals, 0, end subscript, start superscript, m, end superscript, a, start subscript, k, end subscript
Find m.
m, equals
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, start text, p, i, end text or 2, slash, 3, space, start text, p, i, end text
Write an expression for a, start subscript, k, end subscript in terms of k.
a, start subscript, k, end subscript, equals
