The value of "x = 15".

Step-by-step explanation:

The given series are:

10, 5, 5, 7.5, x, 37.5

To find, the value of x = ?

The pattern follow,

\times 0.5 ,\times 1,\times 1.5,\times 2,\times 2.5.×0.5,×1,×1.5,×2,×2.5.

5=10\times 0.5=55=10×0.5=5

5=5\times 1=55=5×1=5

7.5=5\times 1.5=7.57.5=5×1.5=7.5

Similary,

x=7.5\times 2=15x=7.5×2=15

37.5=15\times 2.5=37.537.5=15×2.5=37.5

Hence, the value of "x = 15".
