Question

Using the same algorithm:

• Start with a number and add 2 to it.
• Double the result.
• Subtract 3 from that quantity.
If an input to this function is n = 3, what is the output?

Answer 1

7

Explanation:

step 1

`n+2`

step 2

`2(n+2)\\\\=2n+4`

step 4

`2n+4-3\\\\=2n+1`

if n=3

`2(3)+1\\\\=6+1\\\\=7`

output is 7
