Answer:
109
Step-by-step explanation:
Given that there is a sequence of numbers as
4,11,25,53,...
We have to find the next number.
To find the next number, let us see the pattern from the given four numbers
We have
I number = 4
II number = 4+7
III number = II number + 2(7)
Iv number = III number +4(7)
So if we guess this pattern continues the next number namely v number would be
V number = IV number +8(7)
=53+56
109
i.e. I number is added by 7, II number by 2(7), III number by 2^2(7)
hence next number 2^3(7)
Answer is 109
