Answer:
En la última fila de la zona general hay 98 asientos y en la zona preferencial hay 564 asientos.
Explicación paso a paso:
= 1 + − 1 ×
40 = 20 + 40 − 1 × 2
40 = 20 + 39 × 2
40 = 20 + 78
40 = 98
= (1 + ) 2 ×
12= (36 + 58) 2 ×12
12 = 47 × 12
12 = 564

Length of bridge = 53 meters
Length changes expected due to changes in temperature = expansion or contraction by 21 millimeters (or 0.021 meters)
Let length of bridge at any given time be 'a'
As an absolute value equation, the situation can be expressed as:
⇒ |a-53| < 0.021
Solving the equation
⇒ -0.021 < a-53 < 0.021
⇒ 53 - 0.021 < a < 53 + 0.021
⇒ 52.979 < a < 53.021
Hence, the minimum length of the bridge can be 52.979 meters and the maximum length of the bridge can be 53.021 meters.
