Solution:

Required difference

=(1000+950+850+800+650+700)-(900+850+700+700+550+450)

= 4950 – 4150 = 800

=(1000+950+850+800+650+700)-(900+850+700+700+550+450)

= 4950 – 4150 = 800

148

Solution:

Pattern is ×2, ×4, ×6, ×8…

∴ ? = 24 × 6 = 144

∴ ? = 24 × 6 = 144

**Q12. 2, 9, 40.5, 182.25, ?**

820.125

816.125

815.220

812.52

825.12

Solution:

Pattern is ×4.5, ×4.5, ×4.5, ×4.5, ….

∴ ? = 182.25 × 4.5

= 820.125

∴ ? = 182.25 × 4.5

= 820.125
