Given : Seven friends are standing in a queue  A1, A2, A3, A4, A5, A6, A7

The distance between two consecutive friends are same and equal.

Their teacher is standing at point O, maintaining the equal distance as given between two consecutive friends.

To Find :  Seven friends A1, A2, A3 . . .A7 form an

If we consider, common distance is d, and O is point of a origin, what is the value of A7?

Solution:

Seven friends A1, A2, A3 .. .A7 form an  AP

AP - Arithmetic progression

common distance is d, and O is point of a origin, what is the value of A7

a = 0  d = d  A7 = 8th term

A7  = 0 + (8 - 1)d  = 7d

A4   is mid term of ( A1 to A7)
