Question

Answer 1

this is tha answer for finding 6th and 19th term

Answer 2

Answer:

Required 6 th term is 0 and 19 th term is (-26)

Step-by-step explanation:

Given series is 10,8,6,4,...

Here we want to find 6 th and 19 th number of term of the given series.

Here first term of the series is 10 and common difference of the each term is -2

We know in AP series,

nth term $a_n = a + (n - 1)d$

Where a is first term of the series,n is number of term and d is common difference.

So,

6 th number term,

$a_6 = 10 + (6 - 1)( - 2) \\ = 10 + 5 \times ( - 2) \\ = 10 - 10 \\ = 0$

and 19 th number term,

$a_{19} = 10 + (19 - 1) \times ( - 2) \\ = 10 + 18 \times ( - 2) \\ = 10 - 36 \\ = - 26$
