Question

first four terms of an ap are ______ whose first term is -2 and common difference is -2​

Answer 1

here we have a= -2 , d= -2and we have to find first four terms so,

a2=a+d =(-2)+(-2) = -2-2=-4

a3= a+2d = (-2)+ 2(-2) = -2 -4= -6 a4=a+3d=(-2) +3(-2) = -2 -6= -8

a5=a+4d = (-2)+4(-2)= -2 -8 =-10

Here the first four terms are -2,+4,-6
