Question

find the 7th term from the end of AP 7,10,13 ........................184

Answer 1

Answer:

Step-by-step explanation:

Take the AP from the last order (DESCENDING)

184,.......13,10,7

a=184,d=3

A7=a+6d

184+6(-3)

=184-18

=166

The seventh term from the last is 166

Answer 2

your answer

now given to us :-

last term =184

common difference = 3

first term =7

first take out number of terms

l=a+(n-1)×d

184=7+(n-1)×3

184-7/3=n-1

177/3=59+1=60=n

now most important thing is that whenever asked to take out nth term form ap use formula

(n-rth term +1)

so

(60-7+1)=60-6=54

hope helps
