Answer:
The sum of the first, third, and last integer is 1533.
Step-by-step explanation:
Step 1: You need to create a equation first:
n + n + 2 + n + 4 + n + 6 + n + 8 = 2555
How did I make the equation?
If n is odd number, n + 2 must be the consecutive odd number
5 , 5 + 2 , 5 + 4 , 5 + 6 , 5 + 8
5, 7, 9, 11, 13 ALL CONSECUTIVE ODD NUMBERS
Step 2: Simplifying the equation
n + n + 2 + n + 4 + n + 6 + n + 8 = 2555
5n + 20 = 2555
Step 3: Solving the equation, with explanation
5n + 20 = 2555 Subtract 20 on both sides
5n = 2535 Isolate the variable by dividing 5 on both sides
n = 507
Step 4: Plug in the value
n + n + 2 + n + 4 + n + 6 + n + 8
507, 507 + 2 , 507 + 4 , 507 + 6 , 507 + 8
507, 509, 511, 513, 515
Step 5: Solve the sum of the first, third, and last integer
507 + 511 + 515 = 1533
Step 6: THE ANSWER
1533
