Clue 5

Missing addends — the last clue

The security gate requires a target team score to open. We know the current score and just need the missing number that adds up to the winning total to get the last clue.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these
18 + ___ = 21
24 + ___ = 29
4 + ___ = 5
5 + ___ = 15
2 + ___ = 4
18 + ___ = 22
31 + ___ = 37
8 + ___ = 15
23 + ___ = 31
21 + ___ = 30
22 + ___ = 34
Step 2 — cross out the sentence with each answer
1.The villain leaps for an epic diving save, then catches the ball with thermal gloves.
2.The villain executes a wild bicycle kick, then snaps on their magnetic shinguards.
3.The villain slides in with a hard slide tackle, then flashes their bright neon cleats.
4.The villain slides in with a hard slide tackle, then fades away in a stealth jersey.
