Question

1. 12, 112, 212, 312, ... 26) -32, -52, -72, -92, ...

Explanation:

Step1: Analyze the pattern in 25

The difference between consecutive terms: \(112 - 12=100\), \(212 - 112 = 100\), \(312-212 = 100\). The next term is \(312+100 = 412\).

Step2: Analyze the pattern in 26

The difference between consecutive terms: \(-52-(-32)=-20\), \(-72 - (-52)=-20\), \(-92-(-72)=-20\). The next term is \(-92+(-20)=-112\).

Answer:

1. 412
2. -112
