7+23/2=b
30/2=b
b= 15
common difference = 8
7-8= a
a= -1
c= 23+8= 31
so value of a, b , c is -1 , 15 and 31 respectively..
hope it helpss!!!!

Answer:
Step-by-step explanation:
This sequence is in ap so , the difference must be equal,
7-a=23-b=c-23=b-7
7-a=b-7
a+b=14
23-b=b-7
2b=30
b=15
a+b=14
a+15=14
a=-1
, Now
c-23=b-7
c = b+16
c= 15+16
c= 31
I hope u loved it
