1.	For an AP the first term is -8 last term 55 Ifsome of all this term is 235 Find the number of term
Answer» a=-8 last term(TN)=55 sum(Sn)=235 n=? Sn=n/2(a+Tn) 235=n/2(-8+55) 2×235=n(47) n=2×235÷47 n=470÷47 n=10 hence, number of terms=10 hope it helps.. pls MARK it as BRAINLIEST

Answer»

a=-8

last term(TN)=55

sum(Sn)=235

n=?

Sn=n/2(a+Tn)

235=n/2(-8+55)

2×235=n(47)

n=2×235÷47

n=470÷47

n=10

hence, number of terms=10

hope it helps..

pls MARK it as BRAINLIEST
