To complete the missing numbers, first of all we need to write the whole pattern. Therefore:
FIRST.
<em>50, 150, 250,...,1050</em>
The sequence increases at the interval of hundred whose translation in Spanish is cien
In this way, the complete sequence is:
50, 150, 250, 350, 450, 550, 650, 750, 850, 950, 1050
This is written out in Spanish as follows:
<em>Cincuenta (50), Ciento cincuenta (150), Doscientos cincuenta (250), Trescientos cincuenta (350), Cuatrocientos cincuenta (450), Quinientos cincuenta (550), Seiscientos cincuenta (650), Setecientos cincuenta (750), Ochocientos cincuenta (850), Novecientos cincuenta (950), Mil cincuenta (1050)</em>
SECOND.
<em>5.000, 20.000, 35.000,...,95.000 </em>
In this case, the sequence increases at the interval of fifteen thousand whose translation in Spanish is quince mil
Thus, the complete sequence is:
5.000, 20.000, 35.000, 50.000, 65.000, 80.000, 95.000
This is written out in Spanish as follows:
Cinco mil (5.000), Veinte mil (20.000), Treinta y cinco mil (35.000), Cincuenta mil (50.000), Sesenta y cinco mil (65.000), Ochenta mil (80.000), Noventa y cinco mil (95.000)
THIRD.
<em>100.000, 200.000, 300.000,...,1.000.000 </em>
In this case, the sequence increases at the interval of hundred thousand whose translation in Spanish is cien mil
Therefore, by writing the entire sequence we have:
100.000, 200.000, 300.000, 400.000, 500.000, 600.000, 700.000, 800.000, 900.000, 1.000.000
In Spanish, this is written out as follows:
<em>Cien mil (100.000), Doscientos mil (200.000), Trescientos mil (300.000), Cuatrocientos mil (400.000), Quinientos mil (500.000), Seiscientos mil (600.000), Setecientos mil (700.000), Ochocientos mil (800.000), Novecientos mil (900.000), Un millón (1.000.000) </em>
FOURTH.
<em>100.000.000, 90.000.000, 80.000.000,...,0</em>
In this case, the sequence decreases at the interval of ten million that translates into cien millones in Spanish.
Therefore, by writing the complete sequence we have:
100.000.000, 90.000.000, 80.000.000, 70.000.000, 60.000.000, 50.000.000, 40.000.000, 30.000.000, 20.000.000, 10.000.000, 0
We can write this in Spanish as follows:
<em>Cien millones (100.000.000), Noventa millones (90.000.000), Ochenta millones (80.000.000), Setenta millones (70.000.000), Sesenta millones (60.000.000), Cincuenta millones (50.000.000), Cuarenta millones (40.000.000), Treinta millones (30.000.000), Veinte millones (20.000.000), Diez millones (10.000.000), Cero (0)</em>
