《sign》的歌詞作者是日本樂隊Mr. Children。
以下是《sign》的部分歌詞：
I'm a dreamer, I'm a schemer
And I don't mind being different
From the rules, yeah
The dreams may seem unreachable
To you they're like gravity
They're still up there, beating hearts
Let me remind you, in time
(Baby I am here, gonna get real)
Gonna take you higher, higher
(Gonna take you higher)
I'm gonna make it all come true
Yeah, yeah, yeah
I'm gonna sign my name in the sky
With a flash of light and a diamond chain
Gonna rise up high, up high
(Gonna rise up high)
Gonna make it all come true
Yeah, yeah, yeah
Yeah, yeah, yeah, yeah...
You're the flame that lights up my world
And I'm gonna tell you what to do, you'll never walk alone (Yeah)
Follow the fire escape按規律填數，填入合適的位置：347 269 178 271 ( ) 94 。這是一道有趣的規律題，我們可以通過分析來找規律。
分析發現，這個數列中的每個數都比前一個數小70，所以括弧里應該填入的數是 178 + 70 = 248 。因此，空缺處的數字是271後兩位數填為“48”。所以數列的排列順序為：347 269 178 271 248 94。
