a, 7 , b , 23 , c are in AP

so, 7 - a = b - 7 = 23 - b = c -23

-b - a = -14

a + b = 14 --------(1)

2b = 30

b = 15

put this in equation (1)

a = -1

now , again ,

b + c = 46

c = 46 -15 = 31

Answer:

Step-by-step explanation:

23-b=b-7

23+7=2b

30/2=b

b=15

b-7=7-a

15-7-7=-a

a=-1

c-23=23-b

c=23-15+23

c=31
