Question

If the sum of first three terms is 39 and product of first and third term is 144.Find the common difference

Answer 1

Step-by-step explanation:

x+x+x=39

3x=39

x=13

1 term =13

3 term = 13x=144

=11.07

2 term=13+11.07+x=39

= 24.07+x = 39

x =39-24.07

=14.93

All the three terms = 13 , 11.07 , 14.93
