Question

Find the 7th term from the end of AP 7, 10, 13,......184?​

Answer 1

Answer:

Given:

(a)n =184

a+(n-1)d=184

7+(n-1)3=184

7+3n-3=184

4+3n=184

3n=184-4

3n=180

n=180/3

n=60

a(7)=a+(n-1)d

a(7)=7+(7-1)3

a(7)=7+18

a(7)=25

Answer 2

Hello !!

Find the common difference.

d = (An - Ak)/(n - k)

d = (13 - 10)/(3 - 2)

d = 6/1

d = 3

Find the the 7th term.

An = Ak + (n - k) × d

A7 = 13 + (7 - 3) × 3

A7 = 13 + 4 × 3

A7 = 13 + 12

A7 = 25

Therefore, we have the conclusion that the 7th is 25.

I hope I have collaborated !
