Question

Find the missing number.

$3,1.5,1.5,2.25,4.5,.....$

• A. $7.5$
• B. $9.25$
• C. $11.25$
• D. $13.75$

Answer 1

The correct option is C $11.25$

Here,

$3\times 1=3$

$3\times 0.5=1.5$

$1.5\times 1=1.5$

$1.5\times 1.5=2.25$

$2.25\times 2=4.5$

Similarly, $4.5\times 2.5=11.25$

Hence, the correct answer is $11.25$.
