8​

Answer 1

Answer:

y=7

Step-by-step explanation:

1.2

2.3.5

3.4

4.y

5.8

2nd term - 1st term=1.5

3rd term- 2nd term=0.5

AND 3rd term is double of 1st

With that in mind;

the difference between 4th term and 3rd term should be double of 1.5,i.e;3. So 4th term is 7.

To prove it, difference between 5th and 4th term should be double of 0.5,i.e;1. So 5th term is 8.
