Answer 1

Answer:

Given that

nth term of the sequence is 4n + 3.

Let f(n) denote the nth term of the sequence

f(n) = 4n + 3

To find the difference between 50th term and 45th term,

f(50) = 4 × 50 + 3

= 203

f(50) = 203

f(45) = 4 × 45 + 3

= 183

f(45) = 183

Difference between 50th term and 45th term = f(50) − f(45)

= 203 − 183

= 20

Therefore, the difference between 50th term and 45th term is ′20′.
