If the sum of three consecutive natural numbers is 30, find the middle number among the three natural numbers.
30 0 3 1 [OP_SUB] 1 [OP_LIST_ARANGE] [OP_LIST_SUM] [OP_SUB] 3 [OP_DIV] 3 2 [OP_FDIV] [OP_ADD]
var_a = 30
var_b = 0
var_c = 3
var_d = 1
var_e = var_c - var_d
var_f = 1
list_a = [i for i in range(var_b, var_e + 1, var_f)]
list_a = [float(i) for i in list_a]
var_g = sum(list_a)
var_h = var_a - var_g
var_i = 3
var_j = var_h / var_i
var_k = 3
var_l = 2
var_m = var_k // var_l
var_n = var_j + var_m
print(int(var_n))
