Question

What is the difference between?
0 3 4 7

Answer 1

The difference is 0

For the first summation ;

• 2i + 1

For i = 1 to i = 4

2(1) + 1 = 3

2(2) + 1 = 5

2(3) + 1 = 7

2(4) + 1 = 9

Sum = 3 + 5 + 7 + 9 = 24

For the second summation ;

• 2n + 1

For n = 1 to n = 4

2(1) + 1 = 3

2(2) + 1 = 5

2(3) + 1 = 7

2(4) + 1 = 9

Sum = 3 + 5 + 7 + 9 = 24

Difference = 24 - 24 = 0

Hence, the difference is 0
