Question

How do i find the nth sequence in this sequen 7cm 10cm 13cm 16cm

Answer 1

Answer:

$a_{n}$ = 3n + 4

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence

10 - 7 = 13 - 10 = 16 - 13 = 3

This indicates the sequence is arithmetic with nth term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 3 , then

$a_{n}$ = 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

Answer 2

Answer:

This is a sequence of 3 added to digits which start from 7 so 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43, 46, 49, 52, 55, 58, 61, 64, 67, 70, etc.

If u wanna find the 9th sequence the answer is 31
