Answer:
5 ⋅ ( n + 1 )
Explanation:
To write Five times the sum of a number and one you first make "a number" into a variable. In this case let's call it n
Next let's create the sum of a number and one. This would be:
n + 1
sum references addition
Then to get five times this number we need to multiple this expression by five to get: 5 ⋅ ( n + 1 )
