Can you explain number 14 in diagnostic drill 3?
I tried solving it and i read the explanation of patterns.
i got the repeating units of the sequence which is 1,4,6,4,6,4,6
when he asked for the 53rd term should I divide 53 by 3 or 2?
I got confused because the one isn’t repeated again in the pattern.

Thanks in advance =)

For this one, the shortcut is to recognize that after the first term, every odd-numbered term is 6 and every even-numbered term is 4. The 53rd term is an odd-numbered term, so it’ll be 6.
