Abstract :
In this paper, authors proved the generalized Ulam - Hyers stability of system of additive functional equations
egin{align*}
&fleft(sum_{a =1}^{n}~a~x_a ight)
=sum_{a =1}^{n}left(a~f(x_a) ight);qquad ngeq1
&gleft(sum_{a =1}^{n}~2a~y_{2a} ight)
=sum_{a =1}^{n}left(2a~g(y_{2a}) ight);qquad ngeq1
&hleft(sum_{a =1}^{n}~(2a-1)~z_{2a-1} ight)
= sum_{a =1}^{n}left((2a-1)~h(z_{2a-1}) ight);qquad ngeq1
end{align*}
where $n$ is a positive integer, which is originating from sum of first $n$, natural numbers, even natural numbers and odd natural numbers, respectively in various Banach spaces.
