The Pattern is:

$3$

$3 × 3.5 = 10.5$

$10.5 × 3.5 = 36.75$

$36.75 × 3.5 = 128.625$

$128.625 × 3.5 = 450.187$

Therefore,

Correct option A) 450.187

Answer 2

hello mate here is your answer

Here its pattern is repeated by multiplication or multiplying by 3.5

here if you verify by multiplying

=> 3 x 3.5 = 10.5

=> 10.5 x 3.5 = 36.75

=> 36.75 x 3.5 = 128.625

=> 128.625 x 3.5 = 450.1875 or 450.187

here the observation we made is that the pattern has constant repition of number 3.5 by multiplying.

Here we got 3.5 by dividing the product with the multiplicand

Eg : 36.75 is our product when 10.5 x 3.5
similarly when we divide 36.75/10.5 = 3.5

Eg ( 2 ) : 128.625 is our product

so when divide it with 36.75 = 128.625/36.75
we get our answer = 3.5

You can even verify and take a probe or check the answer you will observe that the answer so obtained is 3.5, hence we multiplied 3.5 to obtain the next number in the sequence

hope it helps you
