HOPE THIS HELPS YOU...THANKYOU DEAR ❤

Answer 2

Answer : A.P. will be 3,6,9,12,15,18,21,24,27,30 ✔️

Solution :

Let, the first term of A.P. be 'a' and common difference be 'd'

Given that :

2nd term and 10th term of A.P. are 6 and 30 respectively

As we know that :

Tn = a + (n-1)d

According to the question :

T2 = a+(2-1)d

=> 6 = a+d ...(1)

And T10 = a+(10-1)d

=> 30 = a+9d ....(2)

On subtracting equation (1) from (2) :

8d = 24

=> d = 3

On putting the value of d in equation (1) :

a+3 = 6

=> a = 3

So, A.P. will be 3,6,9,12,15,18,21,24,27,30

I hope it will be helpful for you ☺️
