is it D?

i didn't have scratch paper but i basically multiplied out the very last numbers since they are the only ones that change.

4 * 6 * 8 = a sequence of 24. 24/14 = 10 remainder.

if i had scratch paper, i probably would have multiplied out 14*16*18 and seen how that would have turned out.

4 * 6 * 8 = 192 / 14 gives remainder 10. But I am not sure if this method is correct to solve this problem.

your method is correct but i don't think answer is.

14414/14 = remainder 8

14416/14 = remainder 10

14418/14 = remainder 12

so 8*10*12 = 960/14 = remainder 8

so A should be the answer.

14420 is divisible by 14 so is 14406 then we can write 14406 as amultiple of 14

That is 14406 = 14K for some integer K

14414*14416*14418 /14 =(14K+8)(14K+10)(14K+12)/14


= (14(z)+8*10*12)/14 = Z+8*10*12/14

so the remainder is 8

what about taking the last 2 digits:

14/14 no remainder

16/14 remainder 2

18/14 remainder 4


2*4 = 8
