b. resolver la ecuación

Explanation:

Step1: Analyze Problem 1

The sequence is 24, _, 26, 27. The pattern is increasing by 1. So 24 + 1 = 25 (velnticinco is 25 in Spanish).

Step2: Analyze Problem 2

Sequence: 12, _, 32, 42. The pattern is adding 10. 12 + 10 = 22.

Step3: Analyze Problem 3

Sequence: 29, _, 31, 32. Pattern: +1. 29 + 1 = 30.

Step4: Analyze Problem 4

Sequence: 21, _, 25, 27, 29. Pattern: +2. 21 + 2 = 23.

Step5: Analyze Problem 5

Sequence: 4, 14, _, 34, 44. Pattern: +10. 14 + 10 = 24.

Step6: Analyze Problem 6

Sequence: 101, _, 99, 98. Pattern: -1. 101 - 1 = 100.

Step7: Analyze Problem 7

Sequence: 5, 10, 15, _, 25. Pattern: +5. 15 + 5 = 20.

Step8: Analyze Problem 8

Sequence: 15, 30, 45, _, 75. Pattern: +15. 45 + 15 = 60.

Step9: Analyze Problem 9

Sequence: 90, _, 50, 30, 10. Pattern: -20. 90 - 20 = 70.

Step10: Analyze Problem 10

Sequence: 25, 30, 35, _, 45. Pattern: +5. 35 + 5 = 40.
