Step-by-step explanation:
Sequence is defined as arrangement f numbers in a specific or defined pattern. Sequence are categorized into
1) Arithmetic
2) Geometric
Arithmetic sequence are characterized by their common difference while Geometric sequence are characterized by their common ratio.
Given a sequance of numbers say;
T1, T2, T3...
The first term "a" of the sequence is T1
Common difference d = T2-T1 =T3-T2
Common ratio = T2/T1 = T3/T2
The formula for calculating nth term of an Arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
The nth term of a Geometric sequence is expressed as;
Tn = ar^{n-1}
r is the common ratio
Answer: n=-36
Step-by-step explanation:
Let the number be n
2 fewer than a doubled number can be written as 2n-2
The number decrease by 38,can be written as n-38
Equate both
2n-2=n-38
Collect like terms
2n-n=-38+2
n=-36
The number is -36
I'm not 100% sure this is right but I think this is how you do it
