Question

if first term and second term of a hp are a and b then its nth term will be​

Answer 1

Answer:

next will be c

Step-by-step explanation:

Answer 2

Step-by-step explanation:

1/a =a (first term) , d= 1/b-1/a= a-b /ab

•an =1/a+(n-1)d

•now put the values of a and d

•an = 1/ a+(n-1)(a-b/ab)

TAKING THE LCM OF AB

•an = 1/ b+(n-1)(a-b/ ab)

• an = ab /b+(n-1)(a-b)

Therefore answer is option (C)
