Solution:
Step 1: Understand the operations:
Values = 3 to 7 = 3, 4, 5, 6, 7
Equation = 2n - 3
Step 2: Put the values in the equation:
For n = 3
2(3) - 3 = 3
For n = 4
2(4) - 3 = 5
For n = 5
2(5) - 3 = 7
For n = 6
2(6) - 3 = 9
For n = 7
2(7) - 3 = 11
Step 3: Add all the results:
= 3 + 5 + 7 + 9 + 11
= 35
