Add 2, add 3, add 4, add 5. It's a sequence. Keep it simple.

@zack12drummer

You made that way more complicated than it needed to needed to be lol

@RalphMiles-l6y

It simple my guy. The sequence is 2 ,3 4 5 is the pattern. 1+2 =3, 3+3=6 , 4+6=10, 10+5=15

@AV-hj3cr

Why make it complicated when it's very simple?

@stevenschmidt4441

wtf. it adds by 2 then 3 then 4 then 5. thats how i got to 15.

@reginaldpayne7588

15. There is a numeric gap of sequential ascending numbers as such: btwn 1&3= 2, btwn 3&6= 3, btwn 6&10= 4 SO the next logical numeric sequence would be 15.

@jenniferbreidenbach579

Don't make it so hard. These tests are timed, you need to get to the correct answer as fast as possible, and keep moving.

@OriginalOkie

Wtf. Made that way harder than it needed to be lol 😂

@lis-ub3lz

Its just simple as counting numbers ..1(,2,3)=2
(4,5,6)=3
(7,8,9,10)=4
(11,12,13,14,15)=5

@morveman_yt9567

It called triangles numbers and are made by adding every natural number ex: 3 = 2+1
      6 = 3+2+1
So 15 is 1+2+3+4+5

@lebeg_beats

I did 3-1 wich is 2
6-3, wich is 3
And then 10-6 wich is 4
So the next logical nuber whould be 5,
10+5 is 15
I got the right answer but in a different way

@takeontravel9076

That was too much work. 1-3 add 2 3-6 add 3 6-10 add 4 then add 5, 15

@Miloshx07

Lets make it 100  times more complicated than its need to be. Great job !!!😅😅😅

@VSaranara

This is specifically the number of circles that form a triangle
Basically the summation to 1 to n where n is how many times it is summed

1
1+2
1+2+3
1+2+3+4
1+2+3+4+5
1+2+3+4+5+6

It is the 3rd diagonal of the pascals triangle
1st ones
2nd Natural Numbers
3rd Triangular Numbers
4th Pyramidal Numbers

@illmade2

wow, what a convoluted way to come up with the answer.

@mrintegrity6686

Made that a lot harder to understand than needed

@GojoANIMELOVER-0021

Cool thanks 🙏🏻😅😮

@sanketsarangi5170

Different between each number is increasing by 1, starting from 2,3,4. So the next number would be 10+5 = 15

@commirevo89

This should say "sequence", not series, as a series in mathematics means each term is being added.

@theDOUBTINGthomas010

Congrats you've given me stress with this piece of cake🤣🤣❤
