Question

The 10th term of the Arithmetic progression -3, -1, 1, 3 .is​

Answer 1

Answer:

a=-3

d=2

a_10=a+(n-1)d

a_10=-3+(10-1)2

a_10=-3+9*2

a_10=-3+18

a_10=15

Answer 2

Answer: The series mentioned here in the question is arithmetic series with the first term(a) as -3 and the common difference(d) as 2. we have to calculate the 10th term of the arithmetic series in this question.

The 10th term of AP is 15.

Step-by-step explanation:

Given AP: -3,-1,1,3,…..

Here,

First term = $a_{1}$ = -3

Common difference = difference of consecutive terms= d = -1 –(- 3) = 2

The 10th term of AP is

$a_{10}$=$a_{1}$+(n-1)d

=-3+(10-1)2

=-3+18

=15

Hence, The 10th term of AP is 15.
