Solution:

Pattern is +339×1, +339×2, +339×4, +339×8, +339×16

∴ ? = 2812 + 339 × 8 = 5524

∴ ? = 2812 + 339 × 8 = 5524

**Q8. 156, 468, 780, ? , 1404, 1716**

Solution:

Pattern is +312, +312, +312, +312…..

∴ ? = 780 + 312 = 1092

∴ ? = 780 + 312 = 1092

**Q9. 172, 283, ? , 838, 1282, 1837**

615

Solution:

Pattern is +111×1, +111×2, +111×3, +111×4

∴ ? = 283 + 111 × 2 = 505

∴ ? = 283 + 111 × 2 = 505

**Q10. 8, 12, ? , 88, 356, 1784**

Solution:

Pattern is ×1+4, ×2+4, ×3+4, ×4+4, ×5+4…………

∴ ? = 12 × 2 + 4 = 28

∴ ? = 12 × 2 + 4 = 28
