18, 22, 27, 33, 40, ?

A.

47

B.

48

C.

50

D.

49

Correct option is B

Given: 18, 22, 27, 33, 40, ?
Logic: The pattern is: +4, +5, +6, +7
Find the differences between consecutive terms:
18 + 4 = 22
22 + 5 = 27
27 + 6 = 33 
33 + 7 = 40
Next difference will be 8:
40 + 8 = 48
Thus, the correct option is (b) 48.
