I dont think GMAT would ever ask such question.

I would definitely write them out and add, if in the test.

Depending on the options, we can guess too.

2+3+5+7+11+13+17+19+23+29+31+37+41+43+47+53+59+61+67+71+73+79+83+89+97


= 1060?

ok, thank you for your response! i didn't know if there exist a formula for this...

by the way, what does a "serie of consecutive integers" exactly mean?

is it just

1, 2, 3, 4, 5, ...

or could it also be

5, 10, 15, 20, ... or 2, 4, 6, 8, ...

or even

3, 7, 11, 13, ...

thanks a lot

Consecutive integers should always be consecutive numbers.

1,2,3.. are consecutive integers.

52,53,54... are again consecutive integers.

But, 5,10,15 are not consecutive.

Hope this helps!!

ok, so otherwise they will write for example "consecutive prime numbers" or "consecutive even numbers"...

thank you
