Question

write 15th term of an A.P. in its general form​

Answer 1

15th term of an A.P. in its general form

= A15

Answer 2

To find:

The general form of 15th term of an A.P

Calculation :

Let a be the first term of the arithmetic progression and d be the common difference.

The nth term of an A.P is given by the formula

 Tₙ = a + (n-1)d

15th term is given by

=> T₁₅ = a + (15-1)d

=> T₁₅ = a + 14d

The general form of 15th term of ab A.P is a + 14d
