Question

Find a and b such that the numbers a, 9, b, 25 form an AP. ​

Answer 1

Answer:

A=1, B= 17

Step-by-step explanation:

Given A.P. a,9,b,25.....

difference between two consecutive terms is d(common difference)

difference between 9 and 25 in above question is 2d

So, 2d = 25-9 since a4-a2 = 2d

d = 8

Substituting in a +3d and a+ 2d, you get a and A3

which are 1 and 17 respectively

Hope answer is satisfactory
