Question

The nth term of a sequence is 3n+2
a)work out first three term of sequence.
b)work out the tenth term of the sequences

Answer 1

Answer:

5, 8, 11 and 32

Step-by-step explanation:

To find any term from an nth term formula, substitute the value of the term's position for n. that is

given $a_{n}$ = 3n + 2, then

(a)

$a_{1}$ = (3 × 1) + 2 = 3 + 2 = 5

$a_{2}$ = (3 × 2) + 2 = 6 + 2 = 8

$a_{3}$ = (3 × 3) + 2 = 9 + 2 = 11

(b)

$a_{10}$ = (3 × 10) + 2 = 30 + 2 = 32
