1.	What is the tenth term of 11 9 7 5 3 1
Answer» $\star\green\boxed{\bf ANSWER}}\star$ Given : Series : 11, 9, 7, 5, 3, 1 To Find : Tenth term of the series. Solution : Given series is in ARITHMETIC progression (AP) AP : 11, 9, 7, 5, 3, 1 Here, First term, a = 11 common DIFFERENCE, d = 9 - 11 = -2 n = 10 Let, tenth term be a10. nth term of an AP, an = a + (n - 1)d $\implies$ a10 = 11 + (10 - 1)-2 $\implies$ a10 = 11 - 18 $\implies$ a10 = -7 Therefore, 10th term = -7.

$\star\green\boxed{\bf ANSWER}}\star$

Given :

Given series is in ARITHMETIC progression (AP)

AP : 11, 9, 7, 5, 3, 1

Here,

First term, a = 11

common DIFFERENCE, d = 9 - 11 = -2

n = 10

Let, tenth term be a10.

nth term of an AP, an = a + (n - 1)d

$\implies$ a10 = 11 + (10 - 1)-2

$\implies$ a10 = 11 - 18

$\implies$ a10 = -7

Therefore, 10th term = -7.
