1. ☞ 50th term of the AP is 750

✭ AP – 15,30,45………

◈ Its 50th term?

Here in the AP we observe that,

So we know that,

Substituting the given values,

2. In the above Question , we have to find the 50th term of the given arithmetic sequence –

15, 30, 45, ………

Here ,seeing the given sequence , we can get the following information –

The initial term, a = 15

Common difference , d = 15

Now , we know that –

The nth term of an ap can be written as –

a_n = a + ( n – 1 ) d

=> a_50 –

=> a + 49d

=> 15 + 49 × 15

=> 50 × 15

=> 750

Thus , the 50th term of the given AP is 750 .

This is the required answer …….
