Explanation

Working backward from the given sequence: 16, 17, 22, 23, 28. The pattern is add 1, then add 5, alternating: 16+1=17, 17+5=22, 22+1=23, 23+5=28. Going backwards: 16-5=11, 11+1=12(no), wait. Forward: 10+1=11, 11+5=16, 16+1=17, 17+5=22, 22+1=23, 23+5=28. This fits perfectly.

AI explanation

The sequence follows an alternating pattern of adding 1 then adding 5: 10, 11 (+1), 16 (+5), 17 (+1), 22 (+5), 23 (+1), 28 (+5). Filling in the missing term between 10 and 16 using the +1 step gives 11.
