Question

Fimd the cost of carpetting a room 13 by 9 m with a carpet of width 75 cm at 105 per metre cost​

Answer 1

The given AP is   6,734,912,1114……..

First term = 6, common difference =   (734−6)

=   (314−6)

=   74

a = 6, d =   74

The nth term is given by

Tn = a + (n-1) d

T14 = 6 + (37 – 1)  (74) = 6+ 63 = 69

Hence, 37th term is 69
