Question

Which expression can be used to determine the number of downloads on the meh day after the game was available

Answer 1

we have the sequence

1,790 2,555 3,320 4,085 4,850

so

a1=1,790 ----> first term

a2=2,555

a3=3,320

a4=4,085

a5=4,850

Find out the difference between consecutive terms

a2-a1=2,555-1,790=765

a3-a2=3,320-2,555=765

a4-a3=4,085-3,320=765

a5-a4=4,850-4,085=765

This is an arithmetic sequence

The common difference is d=765

so

`a_n=a_1+d\left(n-1\right)`

we have

d=765

a1=1,790

substitute

`\begin{gathered} a_n=1,790+765(n-1) \\ a_n=1,790+765n-765 \\ a_n=1,025+765n \end{gathered}`

The answer is option B
