Explanation

The series follows an alternating pattern: +16, -20, +24, -28, +32, -36. 112+16=128, 128-20=108, 108+24=132, 132-28=104, 104+32=136 (not 134), 136-36=100. Thus, 134 is the wrong number.

AI explanation

This series uses an alternating pattern of subtracting and adding multiples of four. The sequence goes 112 minus 4 is 108, 108 plus 8 is 116, 116 minus 12 is 104, 104 plus 16 is 120, and 120 minus 20 is 100. This logical progression indicates that the number 134 is incorrect.
