-1+(2^(2))/(2!)-(2^(3))/(3!)+(2^(4))/(4!)-....=

If 1^(2)+(2^(2))/(2!)+(3^(2))/(3!)+(4^(2))/(4!)+....=ae,(1^(2).2)/(1!)+(2^(2).3)/(2!)+(3^(2).4)/(3!)+...=be,(1)/(2!)+(1+2)/(3!)+(1+2+3)/(4!)+...=ce then the descending order of a,b,c is

(a^(2))/(2) + (b^(3))/(3) - (3c^(3))/(4) + (a^(2))/(3) - (3b^(3))/(4) + (c^(2))/(2) - (3a^(2))/(4) + (b^(3))/(2) + (c^(3))/(3) = "______"
