SUM AND PRODUCT OF NUMBERS

The product of three consecutive terms of a G.P. is 64. The sum of product of numbers taken in pair is 56. Find the numbers.

The product of three consecutive numbers in G.P. is 27 and the sum of the products of numbers taken in pair is 39. Find the numbers.

The sum of three numbers in AP is -3 and their product is 8, then sum of squares of the numbers is

The sum of two numbers is 7 and the sum of their squares is 25. The product of the two numbers is:

If the continued product of three numbers in GP is 216 and the sum of their products in pairs is 156, then find the sum of three numbers.

The sum of two numbers is 22 and product is 120. The numbers are:

If A={1,2,3,4,5,...,...,15} , then the sum of all products of numbers by taking two or more numbers from the set A is (16!-n) . Then [(n)/(13)] is equal to, where [.] denotes G.I.F.),
