Question

if the first term of a.p is a and nth term is b then it's common difference is of a.p is a and nth term is b, then its common difference be

Answer 1

the first term of AP is =a
the end term of AP is=b
a+(n-1)×d= b
if the common difference is a
the nth term is b
a+(b-1)×a=b
a+ab-a=b
ab=b
a=b/b
a=1

Answer 2

Answer:

1

Step-by-step explanation:

FIRST TERM = COMMON DIFFERENCE = a

nth term = b

therefore,

a+(n-1)d = b

or, a+(b-1)a = b

or, a+ab - a = b

or, ab=b

or a = b/b = 1

therefore,

common difference = 1
