1+8

1+15

Number 2 Square pairs: 2+7

2+14

Number 3 Square pairs: 3+1

3+6

3+13

5+4

5+11

Number 6 Square pairs:: 6+3

6+10

Number 7 Square pairs: 7+2

7+9

Number 8 Square pairs: 8+1 Number 9 Square pairs: 9+7

9+16

Number 10 Square pairs: 10+6

10+15

Number 11 Square pairs: 11+5

11+14

Number 12 Square pairs:12+4

12+13

Number 13 Square pairs:13+3

13+12

Number 14 Square pairs:14+2

14+11

Number 15 Square pairs:15+1

15+10

Number 16 Square pairs:16+9

As can be seen, there are two numbers that can form a pair in only one way: 8 and 16. Therefore, these two numbers need to be at the start or at the end of the sequence. If we start with the number 16, the sequence follows almost automatically: 16 9 7 2 14 11 5 4 12 13 3 6 10 15 1 8. Of course, the reverse sequence is also a possible solution.

98 - 102 = 96

98 - 02 * 1 = 96

5 = 30

4 = 20

2 = ?

8

What am I?

The letter “t”.

Habit! Remove h and "a bit" remains; remove a and "bit" remains; remove b and "it" remains.

Which two numbers should replace the question marks?

Starting at 19, alternate numbers progress +2, +3, +4, +5.

Starting at 20, alternate numbers progress +2, +4, +6, +8.

45 days.

24 * 15 = 8 * X

X = 360 / 8 = 45

Mr. Smith got 3/4th sums correctly. Hence the number of correct sums are 45.

The letter ‘t’ is in the middle of the word ‘water’ and an island is surrounded by water, therefore, in the middle of water.
