Answer 1

Answer:

The answer is

Step-by-step explanation:

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

Answer 2

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.......
