ANSWER
Given that
n
th
term of the sequence is 4n + 3.
Let f(n) denote the n
th
term of the sequence
f(n) = 4n + 3
To find the difference between 50
th
term and 45
th
term,
f(50) = 4 × 50 + 3
= 203
f(50) = 203
f(45) = 4 × 45 + 3
= 183
f(45) = 183
Difference between 50
th
term and 45
th
term = f(50) − f(45)
= 203 − 183
= 20
Therefore, the difference between 50
th
term and 45
th
term is
′
20

Step-by-step explanation:
If n=1, a=-2(1)+3=1
If n=2, a2=-2(2)+3=-4+3=-1
If n=3, a3=-2(3)+3=-6+3=-3.
a=1, d=-2
The sequence is, 1,-1,-3.......
