Question

I’m really bad at the nth term, can anyone help me figure out the nth term of this sequence: 7,10,13,16,19 ...

Answer 1

Answer:

so the answer is 31

Step-by-step explanation:

well first you have to see how much it increases each time

_____________________________________________

so that would be three

so

7_10_13_16_19_22_25_28_31

1    2   3    4   5    6     7     8    9

Answer 2

Answer:

$a_{n}$ = 3n + 4

Step-by-step explanation:

The terms of the sequence form an arithmetic sequence with n th term

$a_{n}$ = a + (n - 1)d

where a is the first term and d the common difference

d = 10 - 7 = 13 - 10 = 3 and a = 7, hence

$a_{n}$ = 7 + 3(n - 1) ← distribute and simplify

                        = 7 + 3n - 3 , hence

$a_{n}$ = 3n + 4
