Find the wrong number in the following number series. $16 \quad 70 \quad 341 \quad 1369 \quad 6841 \quad 27369$

The pattern should be squares of consecutive odd numbers: 1²=1 (but 16 given), 3²=9, 5²=25, 7²=49, 9²=81, 11²=121. Alternatively: ×4+6, ×5-9, ×4+5, ×5-4, ×4+5 pattern. Checking 70: 16×4+6=70, 70×5-9=341, 341×4+5=1369, 1369×5-4=6841, 6841×4+5=27369. The pattern is consistent except 70 appears where 341 should follow 16 directly with ×5-9=71, not 70. Thus 70 is wrong.
