In this problem, we are given four patterns, so we need to write out the missing numbers in Spanish, therefore:
1) 50, 150, 250 ... 1050
This sequence is increasing at the interval of 100 (in Spanish, <em>cien</em>)
Therefore, by writing the complete sequence we have:
50, 150, 250, 350, 450, 550, 650, 750, 850, 950, 1050
This is written out in Spanish as follows:
<em>Cincuenta (50)</em>
<em>Ciento cincuenta (150)</em>
<em>Doscientos cincuenta (250)</em>
<em>Trescientos cincuenta (350)</em>
<em>Cuatrocientos cincuenta (450) </em>
<em>Quinientos cincuenta (550)</em>
<em>Seiscientos cincuenta (650)</em>
<em>Setecientos cincuenta (750) </em>
<em>Ochocientos cincuenta (850) </em>
<em>Novecientos cincuenta (950)</em>
<em>Mil cincuenta (1050)</em>
2) 5.000, 20.000, 35.000 ... 95.000
In this case, the sequence increases at the interval of 15.000 (in Spanish, <em>quince mil</em>)
Therefore, by writing the complete sequence we have:
5.000, 20.000, 35.000, 50.000, 65.000, 80.000, 95.000
In Spanish, this is written out as follows:
<em>Cinco mil (5.000)</em>
<em>Veinte mil (20.000)</em>
<em>Treinta y cinco mil (35.000)</em>
<em>Cincuenta mil (50.000)</em>
<em>Sesenta y cinco mil (65.000)</em>
<em>Ochenta mil (80.000)</em>
<em>Noventa y cinco mil (95.000)</em>
3) 100.000, 200.000, 300.000 ... 1.000.000
In this case, the sequence increases at the interval of 100.000 (In Spanish, <em>cien mil</em>)
Therefore, by writing the complete 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)</em>
<em>Doscientos mil (200.000)</em>
<em>Trescientos mil (300.000)</em>
<em>Cuatrocientos mil (400.000) </em>
<em>Quinientos mil (500.000)</em>
<em>Seiscientos mil (600.000)</em>
<em>Setecientos mil (700.000)</em>
<em>Ochocientos mil (800.000)</em>
<em>Novecientos mil (900.000)</em>
<em>Un millón (1.000.000) </em>
4) 100.000.000, 90.000.000, 80.000.000 ... 0
In this case, the sequence decreases at the interval of 10.000.000 (In Spanish, <em>diez millones</em>)
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
In Spanish, this is written out as follows:
<em>Cien millones (100.000.000) </em>
<em>Noventa millones (90.000.000) </em>
<em>Ochenta millones (80.000.000) </em>
<em>Setenta millones (70.000.000) </em>
<em>Sesenta millones (60.000.000)</em>
<em>Cincuenta millones (50.000.000) </em>
<em>Cuarenta millones (40.000.000) </em>
<em>Treinta millones (30.000.000)</em>
<em>Veinte millones (20.000.000)</em>
<em>Diez millones (10.000.000)</em>
<em>Cero (0)</em>
