Algebra-1

To find the 50th term of the given sequence: 100, 90, 80, 70,...

We can observe that each term is obtained by subtracting 10 from the previous term.

 

Starting from the first term (100), we can use the formula:

=+d×(n−1),

where:

represents the nth term of the sequence,

represents the first term of the sequence (100),

d represents the common difference between the terms (-10),

and n represents the term number we want to find (50).

 

Substituting the values into the formula, we have:
