Find the common difference in an arithmetic sequence in which a10-a20=70.
is tht u on the pic?:o
yes? can u please help me now
if u were real
what is u problem
check out the link
if u don't wanna help screw off
everyones here to help
lol. both of you seem rather like mindless trolls.
i hate fake peoples lmao
math_Hater_ u a$$hole
lol how?
can anybody actually help me
so you're telling that diff. of 10th, 20th term is 70. So let 1st term = a, n1 = 10, n2 = 20, and 10th -20th = 70. If d is common difference - The 10th term = a + (10-1).d => a+9d And 20th term = a + (20-1)d => a + 19d Now 10th term - 20th term = 70. a+9d - (a+19d) = 70. 9d - 19d = 70 70 = -10d. d = -7. Common difference = -7 = ANS.
abc is retarded to pretend to be cute and lie about his pic, rather shallow and retarded, and to use the word "a$$hole". and math_hater- is not-so-smart for bringing it up and picking a fight about it.
and lucky is a genius.
@abc123! your worked out sum is there. cheers :)
thank you my man
lol sorry freakin
who gave this fake guy a medal?
@Math_Hater- am nt faker.
i did
not u lucky
im talking about abc123
