Explanation

The series follows: subtract sum of digits. 436-13=423, 423-9=414, 414-9=405, 405-9=396, 396-18=378, 378-18=360, 360-9=351, 351-9=342... Hmm. Let me check: 436→(4+3+6)=13, 436-13=423. But next is 382. 423-41=382? 4+2+3=9. Not matching. Actually checking: 248→(2+4+8)=14, 248-14=234, then 234→9=225... But series shows 148. The pattern breaks. 248 is the wrong number.
