The correct option is option B.
The common difference between given data is -3/4.
<h3>What is Sequence?</h3>
A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
Here, given points;
x₁ = 1 , x₂ = 2 and y₁ = -3.75 , y₂ = -4.5
Now,
d = (y₂ - y₁)/(x₂-x₁)
d = (-4.5 - (-3.75))/(2 - 1)
d = -0.75 / 1
d = - 75/100
d = -3/4
Thus, The correct option is option B. The common difference between given data is -3/4.

The is no answer in the qustion
In standard form it would be 0.147
Answer:
Step-by-step explanation:
The given complex number is:
Firstly we can solve (2+3i)(4-7i)(1+i)
= 2(8)+2(-7i)+4(3i)+3i(-7i²)× (1+i)
= (16-14i+12i-21i²i)× (1+i)
Since, i² = -1
= (16-14i+12i-21(-1)i)× (1+i)
= (16-14i+12i+21)× (1+i)
= (29-2i)(1+i)
= 31+27i
Denominator : (1-i²)
= (1-(-1))
= 2
Hence, the correct answer is .
