1. The number series is : +(0.5)2, +(1.5)2, +(2.5)2, +(3.5)2, +(4.5)2,……….Hence, C = 16.75
2. The number series is : ×(0.5) + 12, ×1 +(1.5)2, ×1.5 + (2)2, ×2 + (2.5)2, ×2.5 + 32,…….. Hence, D = 42
3. The number series is : × 2 – 12, × 2 + 22, × 2 – 32, × 2 + 42, × 2 – 52,………..Hence, A = 35
4. The number series is :×(.5)2, ×(1)2, ×(1.5)2, ×(2)2, ×(2.5)2, ……….Hence, B = 7
5. The number series is : × 3 – 2, × 4 + 3, × 5 – 4, × 6 + 5, × 7 – 6,…….

Hence, C = 211
