Question

Given the arithmetic sequence 4,7,10,13

Answer 1

Answer:

$b. \: a_n =4+ 3(n-1)$

Step-by-step explanation:

Given Arithmetic sequence is: 4, 7, 10, 13

Here,

First term (a) = 4

Common Difference (d) = 7 - 4 = 3

nth term of an Arithmetic sequence is given as:

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

Substituting the values of a and d in the above sequence, we find:

$a_n = 4 + (n-1)\times 3\\\therefore a_n =4+ 3(n-1)\\\huge \red {\boxed {\therefore a_n =4+ 3(n-1)}}$
