Question

sum of first 14th term of an ap is 50 less than 100 find the 20th term if first term is 10​

Answer 1

Step-by-step explanation:

i think is wrong questions and i know in book like this questions are present

so i do that

S14=1050

a=10 and n=14

by formula sn=n/2(2a+(n-1)d)

1050=7×(2×10+(13)d)

(1050/7)=20+13d

150-20=13d

130/13=d

d=10

a20

a+19d=A20

=10+190 ( d =10)

=200

i hope it helps you
