Quiz Answer Key and Fun Facts

1. Find x for the following pattern: 876, 765, 654, x

Answer: 543

Each digit for every number as the pattern goes on is lesser than each digit of the previous number by 1

2. Find x for the following pattern: 2/3, 4/9, 16/81, 256/6561, x

Answer: 65536/43046721

The next number for this pattern is always the square of the previous number.

3. Find x for the following pattern: 2, 4, 8, 16, 32, x

Answer: 64

2*2 = 4
4*2 = 8
8*2 = 16
16*2 = 32
32*2 = 64

4. Find x for the following pattern: 2, 6, 24, 120, x

Answer: 720

2! = 2
3! = 6
4! = 24
5! = 120
6! = 720

The factorial sign means to multiply the first number by each number lower than itself, so 6! is 6x5x4x3x2x1, or 6 x 120, the previous number in the sequence.

5. Find x for the following pattern: 140, 8.37, 2.05, 1.01, x

Answer: 0.71

(140/2)^0.5 = 8.37
(8.37/2)^0.5 = 2.05
(2.05/2)^0.5 = 1.01
(1.01/2)^0.5 = 0.71

6. Find x for the following pattern: (answer to be rounded off to 2 decimal places.) 0, 0.174, 0.342, 0.5, x

Answer: 0.64

sin(0) = 0
sin(10) = 0.174
sin(20) = 0.342
sin(30) = 0.5
sin(40) = 0.64

7. Find x for the following pattern: (answer to be rounded off to 2 decimal places.) 1, 0.985, 0.906, 0.707, 0.342, x

Answer: -0.17

cos(0) = 1
cos(10) = 0.985
cos(25) = 0.906
cos(45) = 0.707
cos(70) = 0.342
cos(100)= -0.17

8. Find x for the following pattern: 9, 64, 343, 1296, x

Answer: 3125

9^1 = 9
8^2 = 64
7^3 = 343
6^4 = 1296
5^5 = 3125

9. Find x for the following pattern: 252, 736, 1462, 2430, x

Answer: 3640

12 * 21 = 252
23 * 32 = 736
34 * 43 = 1462
54 * 45 = 2430
65 * 56 = 3640

10. Find x for the following pattern: (answer to be rounded off to 3 decimal places.) 0.889, 0.566, 0.401, x

Answer: 0.295

log(60)/2 = 0.889
log(50)/3 = 0.566
log(40)/4 = 0.401
log(30)/5 = 0.295
