Question

if an AP. frist term (a)= -18.9, common diff (d) = 3.6 then find the value of n ​

Answer 1

Answer:

the nth term of the AP is 3.6n - 22.5

Step-by-step explanation:

a = -18.9

d = 3.6

nth term = a + (n-1)d

= -18.9 + (n-1) 3.6

= -18.9 + 3.6n - 3.6

= 3.6n - 22.5

therefore the nth term of the AP is 3.6n - 22.5
