Answer 2

Answer:

10th term in given A.P = 28

Step-by-step explanation:

Given A.P : 1,4,7,10, ...

First term (a) = 1,

$Common \: difference (d)= a_{2}-a_{1}\\=4-1\\=3$

n = 10,

$n^{th}\: term = a_{n}= a+(n-1)d$

$\implies a_{10}= 1+(10-1)3\\=1+9\times 3\\=1+27\\=28$

Therefore,

10th term in given A.P = 28
