Answer:
Can you Please tell me the terms of the A.P. properly.
Step-by-step explanation:
By the way, formula to find nth term in a A.P. is
a + (n-1)d where a is the first term of A.P., n means nth term e.g. if you want to find 21st term of A.P., then type 21 in place of n. Finally d is the common difference which means second term - first term = third term - 2nd term= 4th term - 3rd term= and so on = d
For. e.g. in the following A.P. 1, 3, 5, 7, 9
The common difference d is 2 i.e. 3 -1 = 5-3= 7-5= 9-7 = 2
