6,3,3,4.5,9,22.5 . . .?

The first value i.e 6 is multiplied by 0.5 to get the next number i.e. 3, now to get the next number after this 3 is multiplied by (0.5+0.5=1) to have the third number 3, and in a similar fashion it is multiplied by (0.5+0.5+0.5=1.5) to have the next number i.e. 3*1.5=4.5 and then 4.5 is multiplied by (0.5+0.5+0.5+0.5=2) to get 9 and finally now 9 is multiplied by (0.5+0.5+0.5+0.5+0.5=2.5) to get 22.5; now if you people look at the whole process, it is clear that the number which we multiplied to get the next number is increasing by 0.5,

So we must multiply (0.5+0.5+0.5+0.5+0.5+0.5=3) with 22.5 to get the next number which is 67.5

@Anil

Your question is very good. The answer is 67.5

The series is 6,3,3,4.5,9,22.5,67.5
Explanation:
second number is divided by first number and so on that is
3/6=1/2=0.5
3/3 =1
4.5/3 =1.5
9/4.5 =2
22.5/9 =2.5
The division of difference is increased by o.5
The calculation of last number:
x/22.7 =3 because after 2.5 the difference is 3 thats why
x=3*22.7
x=67.5 this is answer

At whatever point I have a discussion about dresses, I regularly find that the vast majority have a powerful urge on ready made dresses, Why? because ready made stuff is always preferred in this busy schedule life. Yet, here\'s the thing.

53 53 40 40 27 27....

1. 53 + 53 = 106, & divide by 2 = 53,
2.53 - 13 = 40,
3.40 + 40 = 80 & divided by 2 = 40,
4. 40 - 13 = 27,
5.27 + 27 = 54 & divided by 2 = 27,
6.27 - 13 = 14.

If we add 53 and 53 like wise 40 and 40then subtract 106-80 the diff. Is 26 and at last adding 27 and 27 sums to 54 then subtract 26 it's 28 and 28 comes adding 14, 14.

This to simple logic (53, 53, 40, 40, 27, 27).

Total tree numbers in subtracted 53-13 = 40.

40-13 = 27.
27-13 = 14.

The correct answer is 14.

Given:

6, 3, 3, 4.5, 9, 22.5, ?

Write the diff b/w numbers of the given series:

-3, 0, 1.5, 4.5, 13.5,

This is clue to find answer.

Difference between each number is 13, example: 53-40 = 13.
40-27 = 13.

27+13 = 40 similar 14+13 = 27 or 27-13 = 14.
Answer B. 14.

Series 53, 53, 40, 40, 27, 27,.....
So 53 - 13 = 40
40 - 13 = 27
27 - 13 = 14.

So according to me, this answer is 14 correct.

53,53,40,40,27,27....?

Here the one more trick,
