what have you tried?

#

btw not a series, series are infinite sums

#

that’s a strange sequence, as the d between a and the second term is 10 the rest is 15

full swan btw not a series, series are infinite sums

series can be finite

bro what😭

#

idk why there is a 5 there

#

is it just 15+30+45+60?

#

tepid herald series can be finite

no...

#

full swan no...

thats wrong

#

sets can be finite

#

search up finite sets on google

#

theres a definition for that

#

series and sets are different.

#

a series is an infinite sum. we just call it a sum otherwise
a set is a collection of mathematical objects

Definition
A finite series is the sum of a given number of terms in a sequence that comes to an end

#

found this on google

#

ykw you clearly don't want to understand

#

i'll stop

civic root Oct 11, 2024, 10:18 AM

#

anyway just ignore the 5 i think

#

now the series is in the table of of 15

#

so 15 would be a constant outside the summation

#

then just put in a variable
