I think the answer is wrong or I don't know whether I understood wrongly if you use this method for solving the problem then the next number should come correctly. According to your method the next number should be 4718-542=4176 but the next number is 4718 ?

@Jayasree,

Just look at the first 3 digits of every number in the sequence, they are the common difference between that number and next number, eg: '582'4- (582) = 5242.
Now ' 524'2- (524) then we will get the answer.

The sequence is as follows:

5824, (5824-582=5242), (5242-524=4718), (4718-471=4247), (4247-424=3823), which is as per the sequence given.

How will we know that we have to take the first 3 digits of the preceding term?

@Rajwant.

Can you say that how can you guess, as it is 471?
Rajwant said:   1 decade ago
For next number, calculate as follows:

4718-471 = 4247.

@Jayasree.

Consider first 3 digits for subtraction.
