Formulas of AP or Arithmetic Progressions :- 1) For finding the n terms of an AP = a + (n-1)d where a is first term of the AP and d is the comoon difference. 2)For finding the sum of n terms of an AP = n/2(2a + (n-1)d) or n/2(a + l) where l is the last term of the AP. Hope it helps<3

Answer:
AP= a, a+d, a+2d, a+3d.....
Here, a is the first term
And, d is common difference
For finding n terms,
Tn=a+(n-1)d
