Question

What is the next term in the pattern 0.3, 0.5, 0.7, 0.9, ...?

Answer 1

1.1, 1.3, 1.5. Your just adding .2 to the number each time

Answer 2

To find out what is the next term in this pattern we need to find the pattern which we need to add or subtract and in this case it will be add. lets do it:- 

0.3, 0.5, 0.7, 0.9, ___

0.9 - 0.7 = 0.2
0.2 + 0.7 = 0.9
0.7 - 0.5 = 0.2
0.2 + 0.5 = 0.7
0.5 - 0.3 = 0.2
0.2 + 0.3 = 0.5

So to add 0.2 is the pattern. lets do it:-

0.9 + 0.2 = 1.1
1.1 + 0.2 = 1.3
1.3 + 0.2 = 1.5
1.5 + 0.2 = 1.7
and on and on

So, the pattern with the new numbers will look like, 0.3, 0.5, 0.7, 0.9, 1.1, 1.3, 1.5, 1.7.

Hope I helped ya!!
