Question

47 by 11 - 25 by 11​

Answer 1

2,15,4,47,7,118,11,Y,X

It is a combination of 2 series

First one is as follows..

2,4,7,11,X

4-2=2

7-4=3

11-7=4

Their difference forms a series so next number should give a difference of 5

Let it be X

X-11=5

X=16

Next series is

15,47,118,Y

They have a link with the number succeeding them in given question

Number succeeding 15 is 4

Square of 4=16

16-1=15

Number succeeding 47 is 7

Square of 7=49

49-2=47

Number succeeding 118 is 11

Square of 11=121

121-3=118

So now….since we calculated X to be 16

Square of 16=256

256-4=Y

Y=252

Answer 2

Answer:

517-275

242 is the answer
