Question

18 36 72 132 222 ? what comes after that?

Answer 1

Answer:

The missing number of the series is 348.

Step-by-step explanation:

Hey Mate,

Given Series : 18, 36, 72, 132, 222, X

Logic behind this series is triple different base. So, we need to find the difference 3 times in the series.

Diff (1) : 18,  36,  60, 90, 126

Diff (2) : 18,  24,  30, 36

Diff (3) : 6*3, 6*4, 6*5, 6*6

Missing number is  222 + 126 = 348

(#The solution of given series is attach with this answer.)

The Missing number of the series is 348

Answer 2

The missing number is 348.

Step-by-step explanation:

We have,

18, 36, 72, 132, 222, ?

To find, the missing number =

The pattern follow:

+ 18, + 36(18 + 18), + 60(36 + 24), + 90(60 + 30),...

36 = 18 + 18 = 36

72 = 36 + (18 + 18) = 36 + 36 = 72

132 = 72 + (36 + 24) = 72 + 60 = 132

222 = 132 + (60 + 30) = 132 + 90 = 222

Similarly,

? = 222 + (90 + 36) = 222 + 126 = 348

Hence, the missing number is 348.
