I think the first one 's next number will be 913.

It isn't the usual difference between the numbers example 346-289 = 57 It is simply moving the digits around.

34 in the 346 became the last two digits of the 3rd number, as did 28 (from 289)become the last two digits of the forth number. Therefore, I can only suppose that 13 (from the 134) will become the last two digits of the fifth number.

I also assume 62 (from 628)will be the last two digits of the sixth number.

Now that we see that we are simply moving digits and not caculating lets assume that the 6 in 628 came from the last digit in 346. Therefore, lets take the 9 from 289 and stick in in front of the fifth number giving us 913.

If I were going on to the 6th number I'd take the first two digits from 628 (62) and add the last digit from 134 (4) and make the 6th digit 462.

The second one is a matter of moving the digits also. I'd say the answer is "b".

Write down 1798206 and below it write 9826017.

If you haaven't already noticed they all have the same 7 digits in them. Now notice where did the digits move to from 1798206 to create 9826017?

You now need to use the number 9602178 and move it's digits just like the first set and you should have your answer.

HINT: Notice the first two digits (17) moved to the last two of the second number so which answer has 96 as the last two digits?

I hope these are right !
