Question

sum of first 20 terms is -4-2+0+​

Answer 1

Answer:

What do you mean by first 20 terms?

Step-by-step explanation:

By the way

-4-2+0+=

(-4)-(+2)+0

= we see the -(+

and (+)and (-) is (-)

so

(-4)-2+0

now we see

there is '4' negative and '2' positive

so

negative = (-)

positive = (+)

we know (+) and (-) or (-) and (+)=(-)

but here we have to remember two negatives (-) are positive (+)

here we see there is a (-) in front of both 4 and 2

that means they both are negative (-)

So Negative(-) and Negative (-) ?

= Positive (+)

therefore

4+2=6

but the zero is still left

so

6+0=?

yes

6

therefore

ANS = ??

YES

ANS = 6
