так как 31 чисел должны быть четными, то 38-31=7 чисел должны быть нечетными. например, в качестве наименьших нечетных чисел, оканчивающихся на цифру 5, можно взять числа:
5, 15, 25, 35, 45, 55, 65.
их сумма будет равна 245. тогда четные числа в сумме должны давать
1255-245 = 1010.
наименьшие из 31 четных чисел – это последовательность:
2, 4, 6, 8, …, 60, 62
и их сумма равна
.
разница с требуемым значением составляет
1010-992 = 18.
скорректируем последовательность из 31 четных чисел. уберем из нее последнее число 62 и вместо него запишем четное число 62+18=80. таким образом, получили требуемую последовательность чисел.
