What is n^th term of an A.P.?(a) an = a + (n-1) d(b) an = a + (n) d(c)

1.	What is n^th term of an A.P.?(a) an = a + (n-1) d(b) an = a + (n) d(c) an = ar^n-1(d) an = ar^nI had been asked this question by my college professor while I was bunking the class.My doubt is from Arithmetic Progression(A.P.) in division Sequences and Series of Mathematics – Class 11
Answer» The correct choice is (a) an = a + (n-1) d To explain I WOULD SAY: Since every term of an A.P. is incremented by common DIFFERENCE d. i.e. an+1 = an + d = an-1 + 2d = ……. = A1 + n*d or an = a + (n-1) d
