Question

2 + 6+ 10+ 14 + 18 + 22 + 26+ 30+ 34 + 38 = 200

Answer 1

The sum is true.

Answer 2

Sn =  2 + 6+ 10+ 14 + 18 + 22 + 26+ 30+ 34 + 38

Sn = 38 +34 +30 + 26 +22 + 18 +14 +10 +6 +2

2Sn = 40 + 40 + 40 + 40 + 40 +40 +40 +40 +40 +40

2Sn =  40(10)

2Sn = 400

Sn = 400/2

Sn = 200.

But if you wanted to ask the same question as to the page where your link points to then,

No you cannot make 100 by taking any 5 numbers from the list of given numbers.
