Question

Find the missing terms in the series 0.28, 0.56, 1.68.......

Answer 1

Answer:

6.72

Step-by-step explanation:

0.28×2=0.56

0.56×3=1.68

1.68×4=6.72

Answer 2

Answer:  The required missing term in the given series is 6.72.

Step-by-step explanation:  We are given to find the missing term in the following series :

0.28,   0.56,   1.68,    .    .    .  

We see that

if a(n) represents the nth term of the given series, then

$a(1)=0.28,~~a(2)=0.56,~~a(3)=1.68,~~.~~.~~.$

The pattern in the consecutive terms is

$a(2)=2\times a(1)\\\\a(3)=3\times a(2),\cdots$

Therefore, the next term in the given series is

$a(4)=4\times a(3)=4\times1.68=6.72.$

Thus, the required missing term in the given series is 6.72.
