Given a special sequence `a ,b ,c ,d` such that first three number are in A.P. while the last three are in G.P. If the first number is 18 and common ratio of G.P.1/2, then the value of `c+d` is equal to a. 98 b. `10` c. `11` d. 12s

Comprehension (6 to 8) Given a special sequence, a, b, c, d such that first three number are in A.P. while the last three are in G.P. If the first number is 18 and common ratio of G.P. is 1/2 , then answer the following questions The value of c+d is given by 9 (b) 10 (c) 11 (d) 12

Four numbers are such that the first three are in.A.P while the last three are in G.P. If the first number is 6 and common ratio of G.P. is 1/2 the the number are (A) 6,8,4,2 (B) 6,10,14,7 (C) 6,9,12,6 (D) 6,4,2,1

a,b,c,d,e are five numbers in which the first three are in A.P and the last three are in H.P .If the three numbers in the middle are in G.P then the numbers at the odd places are in

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

If a,b,c are unequal numbers in A.P. such that a,b-c,c-a are in G.P. then

The first three of four given numbers are in G.P. and their last three are in A.P. with common difference 6. If first and fourth numbers are equal, then the first number is a. 2 b. 4 c. 6 d. 8

If a ,b ,c ,d are four distinct positive numbers in G.P. then show that a+d > b+c dot

Three numbers a, b and c are in between 2 and 18 such that 2, a, b are in A.P. and b, c, 18 are in G.P . If a+b+c=25 , then the value of c-a is

If x ,2y ,3z are in A.P., where the distinct numbers x ,y ,z are in G.P, then the common ratio of the G.P. is a. 3 b. 1/3 c. 2 d. 1/2

If the first three terms of an A.P are b, c and 2b, then find the ratio of b and c
