Explanation

Difference 1.5 multiply with next power.

2.3 – 4.5 = 1.5^1

6.75–4.5 = 1.5^2

6.75 + 3.75   = 10.125

Answer is 10.125.

Explanation

A + 2 = C 

C + 3  = F

F + 4 = J 

J + 5 = O

Explanation

Looking at the pattern:

20 → 20 (no change)

20 → 19 (decrease by 1)

19 → 16 (decrease by 3)

16 → 17 (increase by 1)

17 → 13 (decrease by 4)

13 → 14 (increase by 1)

14 → 11 (decrease by 3)

Now, we continue the alternating pattern:

11 → 12 (increase by 1)

12 → 9 (decrease by 3)

The next two numbers are 10, 10.

Explanation

Explanation

The pattern appears to be a repeating sequence of:

-2, -2, +3, +3, -4, -4

15 (-2) = 13

13 (-2) = 11

11 (+3) = 14

14 (+3) = 17

17 (-4) = 13

Explanation

Couch, Table and Chair are furniture.

Whereas a rug is a fabric used as a floor covering. Hence, the correct answer is "Rug".

Explanation

0 (since the square of a prime number is not prime)

A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself.

The square of a prime number is not prime because it has at least three divisors: 1, the prime number, and the square itself.

Explanation

 16+12 = 28

Sequence is now: 16,12,28

Take the next two terms of the arithmetic sequence S, 8 and 4

8 + 4 = 12

A sequence is now: 16,12,28,8,4, 12

Explanation

The sequence consists of perfect squares

. The n-th term of the sequence is ((n+2)^2.

3*3  = 9

4*4  = 16

5*5  = 25

6*6  = 36

7*7  = 49
