For the sequence of numbers

Mathematics
1 answer:
Sedbober [7]3 years ago

Answer:

The term rule will be:

a_n=n+21

Step-by-step explanation:

Given the sequence

22, 23, 24, 25, ...

Computing the common difference of all the adjacent terms

22,\:23,\:24,\:25

23-22=1,\:\quad \:24-23=1,\:\quad \:25-24=1

As the difference between all the adjacent terms is the same and equal to

d=1

The first element of the sequence

a_1=22

We know that  An Arithmetic sequence has a constant difference 'd' and is defined by

a_n=a_1+\left(n-1\right)d

substituting a_1=22, and d=1 in the nth term to get the term rule

a_n=a_1+\left(n-1\right)d

a_n=\left(n-1\right)+22

a_n=n+21

Therefore, the term rule will be:

a_n=n+21
