Question

Find the first four terms of the sequence represented by the expression.

Answer 1

Answer:

$8,11,14,17$

Step-by-step explanation:

The rule for the given sequence is

$a_n=3n+5$

To find the first term, we put $n=1$ into the formula to obtain;

$a_1=3(1)+5$

$a_1=3+5$

$a_1=8$

To find the second term, we put $n=2$ into the formula to obtain;

$a_2=3(2)+5$

$a_2=6+5$

$a_2=11$

To find the the third term, we put $n=3$ into the formula to obtain;

$a_3=3(3)+5$

$a_3=9+5$

$a_3=14$

To find the first term, we put $n=4$ into the formula to obtain;

$a_4=3(4)+5$

$a_4=12+5$

$a_4=17$

The first four terms of the sequence is

$8,11,14,17$

Answer 2

Given:
3n + 5

n = 1 ; 3(1) + 5 = 3 + 5 = 8
n = 2 ; 3(2) + 5 = 6 + 5 = 11
n = 3 ; 3(3) + 5 = 9 + 5 = 14
n = 4 ; 3(4) + 5 = 12 + 5 = 17

The first four terms of the sequence are: 8, 11, 14, 17.  Second option.
