What is the next number of the following sequence. 4, 8, 12, 20, 28, 44, .....

G.S.Kantharao   8 years AGO

4, 4*2,4*3,4*5,4*7,4*11 next is 4* 13=52.
Here 2,3,5,7,11 are primes. Next prime is 13. Hence the next is 4*13=52. The right choice is 4.

series of prime numbers multiplied by 4
1 × 4 = 4
2 × 4 = 8
3 × 4 = 12
5 × 4 = 20
7 × 4 = 20
11 × 4 = 44
so next no will be
13 × 4 = 52

It's multiplied by prime numbers.
At first 4 then 4*2=8
then 4*3=12 then 4*5=20 then 4*7=28 then 4*11=44 . 2,3,5,7,11 these all are prime numbers so next will be 4*13=52. which will be the correct answer.

Sohini Chakraborty   8 years AGO

The series represents prime numbered multiples of 4.
(4×1) = 4
(4×2)= 8
(4×3) = 12
(4×5) = 20
(4×7) = 28
(4×11) = 44 and 2,3,5,7,11 is the prime no sequence whose next term should be 13. Hence the required option is (4×13) = 52

Ankush Lakhmani   8 years AGO

In the given numbers of the sequence, each has been obtained by multiplying 4 to the prime numbers starting from 1 till 11.For instance 1*4=4; 2*4=8; 3*4=12 and so on till 11*4=44. Likewise 13 is the next prime number, so 13*4=52. Hence the answer is 52.
