Direction: Directions : What will come in the place of question mark (?) in the following number.
-
4 , 2 , ?, 7.5, 26.25, 118.125
-
- 5
- 4
- 3.5
- 3
- 4.5
Correct Option: D
As per the details in the question the series is in the form of
First term = 4
Second term = First term × 0.5
⇒ Second term = 4 × 0.5 = 2
Third term = Second term × 1.5
⇒ Third term = 2 × 1.5 = ?
∴ ? = 3
Fourth term = Third term × 2.5
⇒ Fourth term = 3 × 2.5 = 7.5 ;
Fifth term = Fourth term × 3.5
⇒ Fifth term = 7.5 × 3.5 = 26.25 ;
Similarly , we can find all others terms also.
Sixth term = Fifth term × 4.5
⇒ Sixth term = 26.25 × 4.5 = 118.125;
Hence , Third term = 3
