Question

The nth term of sequence is 3n -2 is the sequence an AP is so find its 10th term

Answer 1

nth term =3n-2
therefore 10th term =3*10-2=28

if questions like this come for exams don't worry just put the value of the term to be funded in the place of n.

Answer 2

$a_{10} =28.$

Step-by-step explanation:

Given,

$a_{n} =3n-2$

To find, the 10th term of the sequence$a_{10} =?$

Put n = 1, 2, 3, 4, .....,n

$a_{1} =3(1)-2=3-2=1$,

$a_{2} =3(2)-2=6-2=4$,

$a_{3} =3(3)-2=9-2=7$

.

.

$a_{10} =3(10)-2=30-2=28$

∴ The 10th term of an AP,

$a_{10} =28$

Hence, $a_{10} =28.$
