Question :- find the next missing number series

54,28,18,?25,37.5 ?

Solution :-

Logic :- Half of Previous Number + (1² , 2² , ,3² ,4² _____)

Check :-

→ 54

→ (54/2)

→ 27

→ 27 + 1²

→ 27 + 1

→ 28 .

Similarly,

→ 28

→ (28/2)

→ 14

→ 14 + 2²

→ 14 + 4

→ 18 .

Similarly, in Next Now, we will add 3² .

→ 18

→ (18/2)

→ 9

→ 9 + 3²

→ 9 + 9

→ 18 . (Ans.)

Checking Next also, for confirmation :-

→ 18

→ (18/2)

→ 9

→ 9 + 4²

→ 9 + 16

→ 25 .

Also, checking Last, we add 5² Now,

→ 25

→ (25/2)

→ 12.5

→ 12.5 + 5²

→ 12.5 + 25

→ 37.5 .

Hence, Missing Number in the number series is 18.
