Question

10 18 51 200 995
?
(a) 4954
(b) 5964
(c) 5900
(d) 5960
(e) 4964

Answer 1

$10 \times 2 - 2 = 18$

 

$18 \times 3 - 3 = 51$

 

$51 \times 4 - 4 = 200$

 

$200 \times 5 - 5 = 995$

 

$995 \times 6 - 6 = 5964$

Next number will be 5964.

 

Hence,Option $(b)5964$ is the correct choice.

Answer 2

The pattern is as follows:

• $10*2-2=18$
• $18*3-3=51$
• $51*4-4=200$
• $200*5-5=995$
• $995*6-6=5964$

Option (B) is correct.
