Question

find the values ofa, b, c such that the numbers are a, 7,b,23 and c are in ap

Answer 1

HI.....

HERE IS YOUR ANSWER....

7 + d = b ...... (i)

b + d = 23. ...... (ii)

therefore, putting the value of b from (i) in (ii),

7+d + d = 23

7 + 2d = 23

2d = 16

d = 8.

therefore,

a+d = 7

a +8 = 7

a = -1 //

now, 7+d=b

7+8 = b

b = 15//

now, 23+d = c

23+8 = c

c = 31//
