Answer:
The value of 2a - b is 15
Step-by-step explanation:
It has been given here that the given three numbers are in A.P. Now as we know that if the 3 numbers like a, b, c are in A.P. then we will have,
2b = a + c
Hence here we have three numbers which are :
18, a, b-3
∴ 2 a = 18 + b -3
⇒ 2a = 15 + b
⇒ 2a - b = 15
Hence we find the value of the following 2a - b is 15.
