Question

if a=2x+3,d=3x+5 then nth term is

Answer 1

Step-by-step explanation:

Given that:

a=2x+3

d=3x+5

So we have the formula

a(to the base n) = a + (n - 1)d

Now substituting the value

a(to the base n) - 2x-3 = (n-1)(3x+5)

(a(to the base n) - 2x-3) / (3x+5) = n-1

(a(to the base n) - 2x-3) / (3x+5) -1 = n

n = (a(to the base n) - 2x-3 - 3x-5) / (3x+5)

so the nth term is

n = (a(to the base n) -5x-8) / (3x+5)
