Question

Find second and third term of an A.P whose first term is -2 and common difference is -2​

Answer 1

Given first term (a)=−2

Common difference (d)=−2

Tn=a+(n−1)d

T2=a+(2−1)d

     =a+d

     =−2−2

     =−4

T3=a+(3−1)d

     =a+2d

     =−2+2(−2)

     =−2+(−4)

     =−6

∴T2=−4,T3=−6

hope it is helpful pls mark it as brainlist answer

Answer 2

Answer:

-4, -6

Step-by-step explanation:

a= -2 , d= -2 a2=? a=?

a2=a+d

a2= -2+(-2)

a2= -2-2

a2= -4

a3= a+2d

a3= -2+2(-2)

a3= -2-4

a3= -6
