Question

0.5, 0.55, 0.65, 0.8,___
options :
a) 1
b) 0.82
c) 0.9
d) 0.95​

Answer 1

Answer:

a) 1

Step-by-step explanation:

Difference of two consecutive number is forming a series. Lets see.

0.55 - 0.5   = 0.05

0.65 - 0.55 = 0.10

0.8 - 0.65   = 0.15

0.05, 0.10, 0.15 is in a series with difference of 0.05 each.

So, next element is 0.20.

Now,

Let next number of original series be x.

Then,

x - 0.8 = 0.20

x = 1
