Answer:
a_n = 28-2n
Step-by-step explanation:
Given sequence is:
26,24,22,20
We can see that the difference between consecutive terms is same so the sequence is an arithmetic sequence
The standard formula for arithmetic sequence is:
Here,
a_n is the nth term
a_1 is the first term
and d is the common difference
So,
d = 24-26
= -2
a_1 = 26
Putting the values of d and a_1
Hence, the recursive formula for given sequence is: a_n = 28-2n ..
Step-by-step explanation:
Given
as equation 1.
I used q-p as the difference as logically the woman will be older than her son.
Also given,
as equation 2.
Using equation 2,
substitute this equation into equation 1.
Substitute P into equation 2.
Therefore the woman is 45 years old while her son is 15 years old.
