To fill in the gaps, we must first outline the entire pattern. Hence:
FIRST.
50, 150, 250,...,1050
The interval between numbers is one hundred which translates to cien
Therefore, the complete series is:
50, 150, 250, 350, 450, 550, 650, 750, 850, 950, 1050
In Spanish, this can be represented as:
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)
SECOND.
5.000, 20.000, 35.000,...,95.000
In this case, the sequence progresses by fifteen thousand which in Spanish is quince mil
Thus, the entire pattern is:
5.000, 20.000, 35.000, 50.000, 65.000, 80.000, 95.000
The Spanish representation is:
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.
100.000, 200.000, 300.000,...,1.000.000
In this instance, the numbers are increasing by hundred thousand which translates as cien mil
Consequently, listing the full sequence yields:
100.000, 200.000, 300.000, 400.000, 500.000, 600.000, 700.000, 800.000, 900.000, 1.000.000
In Spanish, it is expressed as:
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)
FOURTH.
100.000.000, 90.000.000, 80.000.000,...,0
Here, the series is decreasing by ten million which translates to cien millones in Spanish.
So, writing out the full series gives us:
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
This can be articulated in Spanish as follows:
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)
