D

Can you find the last number in the sequence below?

3 7 15 31 ?

63

Starting with 3:

3 * 2 + 1 = 7

7 * 2 + 1 = 15

15 * 2 + 1 = 31

Continuing this pattern:

31 * 2 + 1 = 63

So, using the pattern of multiplying by 2 and adding 1, the missing number in the sequence is 63.

T = 7777

R = 1111

Y = 5555

N = 4444

E = ?

E = 3333

T = 7+7+7+7 = TWENTY EIFH(T)

R = 1+1+1+1 = FOU(R)

Y = 5+5+5+5 = TWENT(Y)

N = 4+4+4+4 = SIXTEE(N)

3+3+3+3 = TWELV(E)

Continue the sequence by choosing one of the options instead of the question mark.

B.

In every line and column, there are bicycles where 2 of them are facing left, and 1 is facing right, 2 with 2 pedals, and 1 with 12 with a steering wheel and 1 without.

Can you solve the sequence?

Every segment in the new circle moves 90 degrees clockwise.

which plate should be chosen to continue the sequence?

B

every next plate makes a 1/4 turn clockwise.

which number replaces the question mark?

30

Explanation:

As you can see the lower number rows are always bigger than upper row ones with the difference going up by 3 with every step

34 - 32 = 2

32 - 27 = 5 (difference going up by 3 from last difference)

56 - 48 = 8 (difference going up by 3 from last difference)

? - 19 = 11 (difference going up by 3 from last difference)

so ? = 30

Can you find out the number that will replace the question mark?

4.

The 1st picture has 9 connecting dots / crossed lines.

The 2nd picture has one connecting dot / crossed line.

The last picture has 4 connecting dots / crossed lines.

Can you solve the below maths equation problem by replacing the question mark with the correct number?

Note: It has more than one solution.

40 or 96

Explanation:

Solution A :

Add the rhs of the last line to the current line

1 + 4 = 5

5 + 2 + 5 = 12

12 + 3 + 6 = 21

21 + 8 + 11 = 40

Solution B :

RHS = 1ST NUMBER + (1ST NUMBER * 2ND NUMBER)

1 + (1 x 4) = 5

2 + (2 x 5) = 12

3 + (3 x 6) = 21

8 + (8 x 11) = 96

Find the missing number in the table below?

89

(1st-number * 2nd-number) + (1st-number + 2nd-number) = 3rd number.

(3 x 1) + (3 + 1) = 3 + 4 => 7

(6 x 4) + (6 + 4) = 24 + 10 => 34

(8 x 7) + (8 + 7) = 56 + 15 => 71

(9 x 8) + (9 + 8) = 72 + 17 => 89 ... (Answer)
