Question

write the first three terms of the AP those common difference is -3 and the first term is 4

Answer 1

a1=4
d=-3
so a2=a1+d=4-3=1
a3 = 1-3=-2
a4=-2-3=-5

Answer 2

Answer:

So first three terms are 4 , 1 , -2

Step-by-step explanation:

In AP we can get terms by adding common difference of the terms

so

Now we have

a₁ = 4

d = -3

We know that

aₙ = a₁ + (n-1)d              

Now

Second term is

a₂ = a₁ + (n-1)d

Here n = 2 so

a₂ = a₁ + (n-1)d

Putting values

a₂ = 4 + (2-1)(-3)

a₂ = 4 - 3

a₂ = 1

third term is

a₃ = a₁ + (n-1)d

Here n = 3 so

a₃ = a₁ + (n-1)d

Putting values

a₃ = 4 + (3-1)(-3)

a₃ = 4 -6

a₃ = -2
