Find the nth term for the
following sequences:
Q2)3, 9, 15, 21

= 6n - 3

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 9 - 3 = 15 - 9 = 21 - 15 = 6

This indicates the sequence is arithmetic with n th term

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 3 and d = 6, then

= 3 + 6(n - 1) = 3 + 6n - 6 = 6n - 3

answer: there are 453.592 grams in a pound.
