Question

# The mostly played mobile game Pokémon Go completed it’s five years. In the first year the downloads were 0.7 million, in the second year the downloads were 1.4 million, in the next year the downloads were 2.1 million. The probable downloads by the end of 4^{th} year would be

- 2.4 million
- 2.5 million
- 2.8 million
- 3.0 million

Hint:

### Carefully see is there any pattern like increasing or decreasing series.

## The correct answer is: 2.8 million

Solution :

Downloads in 1st year = 0.7 million

Downloads in 2nd year = 1.4 million

Downloads in 3rd year = 2.1 million

If you carefully observe there is a difference of 0.7 million, it means downloads were increasing by 0.7 million every year.

So, as per above series

Downloads in 4th year = download in 3rd year + 0.7 million = 2.1 + 0.7 = 2.8 million

So, there will be 2.8 million downloads in 4th year.
