    Sensacional, nunca tinha visto nada igual,
    sua didática transforma aquilo que é difícil em algo natural, de fácil compreensão, valeu mestre...

    Apenas somei 9+x+7 e igualei a 20. Fazendo os cálculos, também cheguei a 4 para o valor de x.

    Se vc tomar 4 casas seguidas, digamos BCDE, C+D tem que somar 20 com B, e TAMBÉM com E. Então, B tem que ser igual a E (as casas extremas das 4). A casa extrema das 4 que começam com 9, é a anterior a X, logo será tb 9. A casa extrema das 4 que terminam com 7, é a posterior a X, logo será tb 7. Então 9 + X + 7 = 20 ====> X = 4.

    Nota máxima para a didática (só me atrapalho um pouco com o chiado nas palavras, sou de Recife).

    A explicação tá ótima, mas bastava usar a lógica, né? Se todo trio de digitos é 20, significa que são sempre os mesmos números repetidos, então só podia ser 4!

      Exatamente. 9+7+4=20

      9+4+7?

      ​​@@HerberIldefonsoEm raciocínio lógico, não existe coincidência; tudo é questão de lógica.

    Rapaz... Eu só somei 9+7 = 16 e vi que faltava 4 para 20.

    9+x+7=20
    16+x=20
    X=4 , Como são a soma de 3 números quaisquer consecutivos são 20 então o x é consequente do 9 e o 7 é consequente do x, porém a soma deles são 20

    Eu fiz raciocínio rápido 9+7=16
    20-16=(4 resposta),
    9+7+4=20, porque matemática
    complica tanto
    ein? 😂😂

    Creio que há um erro de conceito na elaboração da questão. Pois g=9, x=4 e h=7 não são números consecutivos. (9,4,7). Eu acredito que poderia ser dizer que " a soma de qualquer três números sequencias" .

      Três “dígitos consecutivos” é diferente de “três números consecutivos “
