Step-by-step explanation: d = (am – an)(m – n) so d = (9-5)(7-3) = 1 now an = a + (n-1)d 5 = a + 2×1 {3rd term of the ap} a = 3 so the ap is 3, 4, 5, 6, 7, 8, … where a=3 d=1 Reply
Step-by-step explanation:
d = (am – an)(m – n)
so d = (9-5)(7-3) = 1
now
an = a + (n-1)d
5 = a + 2×1
{3rd term of the ap}
a = 3
so the ap is
3, 4, 5, 6, 7, 8, …
where a=3
d=1
