Answer:
198
Step-by-step explanation:
If the given AP is reversed, then the new AP we will obtain is:
253, ... ..., 13, 8, 3
Now the first term is 253 and common difference = [8-13] = [- 5]
Therefore, the 12th term from last of the AP is the 12th term from the front of the NEW AP
an = a + [n - 1] d
=> a12 = 253 + 11 [- 5]
=> a12 = 253 - 55
=> a12 = 198
