Re: How do I Add Consequetive numbers In Scratch
let's make two variables, v1 and v2. [blocks]
<when green flag clicked>
<set{ v1 }to( 1 )>
<set{ v2 }to( 0 )>
<repeat( 100 )>
<change{ v2 }by( v1 )>
<change{ v1 }by( 1 )>
<end>[/blocks]
That should be it. If you need help, just ask.

Try something like this:
[set [Number] to (0)]
[forever]
[][change [Number] by (1)]
[][add (Number) to [List]]
[end forever]

Code:
(last number in series - first number in series + 1)*((last # + first #)/2)So:
Code:
(100 - 1 + 1)*((100+1)/2) 100*(50.5) 5,050Hope that helps!

He made two identical topics, so they combined them. But I think it didn't work out quite right.
