22. There are two sets of numbers each consisting of 3 terms in A.P. and the sum of each set is 15. The common difference of the first set is greater by 1 than the common difference of the second set, and the product of the first set is to the product of the second set as 7 to 8; find the numbers

In an ordered set of four numbers, the first 3 are A.P. And the last three are in G.P. Whose common ratio is 7//4. If the product of the first and fourth of these numbers is 49, then the product of the second and third of these is :

Two sets have m and k elements. If the total number of subsets of the first set is 112 more than that of the second set, find the values of m and k.

There are two sets A and B each of which consists of three numbers in A.P.whose sum is 15 and where D and d are the common differences such that D-d=1. If p/q=7/8 , where p and q are the product of the numbers ,respectively, and d gt 0 in the two sets . The sum of the products of the numbers is set A taken two at at time is

In a set of four number, the first three are in GP & the last three are in A.P. with common difference 6. If the first number is the same as the fourth, find the four numbers.
