Question

how to find nth term??​

Answer 1

Step-by-step explanation:

Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 .

Answer 2

Answer:

To find nth term we have to know a , n and d .

nth = a + (n-1)d

here,

a = first term of A.P

n = 1,2,3,...

d= different between the A.P

By putting above equation we can get the valueof nth terms.

EXAMPLE :

A.P - 5, 10, 15, 20, .......

find 10th term.

here,

a= 5

n= 10

d= 10-5

= 5

now, putting the values on equation,

nth = a + (n-1) d

10th = 5 + (10-1)5

=> 10th = 5 +9 X 5

=> 10th = 5 + 45

=> 10th = 50

so, the 10th term is 50.
