Question

10,15,20,25. find the nth term of ap
​

Answer 1

Step-by-step explanation:

If you take 25 as an then nth term would be 6

an=a+(n-1)d

25=10+(n-1)5

25-10=(n-1)5

15/5=n-1

3=n-1

n=3+1

n=4

Answer 2

Answer:

Nth term of AP = a+(n-1)d

In the AP 10,15,20,25,...

a = 10

d = 5(15-10)

Nth term = 10+(n-1)5= 10+5n-5 = 5n+5 = 5(n+1)

Therefore the Nth term will be 5(n+1).
