Question

write an AP whose first term is 4 and common alifference is -2​

Answer 1

First term is =4

Common difference=-2

we find AP:-

A1=4

A2=A1+common difference=4+(-2)=2

A3=A2+common difference=2+(-2)=0

A4=A3+common difference=0+(-2)=-2

Then:-

A.P.=4,2,0,-2 (answer)

Answer 2

HERE IS YOUR ANSWER

4,2,0,-2,-4,-6, ............

Step-by-step explanation:

given :- a=4

d=-2

1st term, a=4

2nd term,a2= a+d = 4+(-2) =2

3rd term ,a3=a+2d=4+(2×-2)=0

4th term,a4= a+3d=4+(3×-2)=-2

5th term,a5= a+4d=4+(4×-2)=-4
