Answer (3)

40,20,?,40,20,10? ? = 10 Because, the sequence is 40,20,10 and then replay it again
or
40 - 20 = 20 20 - 10 = 10 40 **** - 20 = 20 20 - 10 = **10
** So, ? = 10 **

It is 10 that ÃŽs missing because the sequence shows that after 20 is 10

The missing number in the sequence 40, 20, ?, 40, 20, 10 is 10. This is because the sequence shows a repeating pattern where it reduces values alternately. Therefore, the complete sequence repeats as expected.
