Question

Find the first four terms of an A.P. whose first term is -2 and common difference is -2.

Answer 1

$\purple{ANSWER}$

a = -2 , d = -2

a1 = a = -2

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

= -4

a3 = a + 2d = -2+2(-2)

= -2- 4

= -6

a4 = a+3d = -2 + 3(-2)

= -2 - 6

= -8

Answer 2

Answer:

first term of A.P=-2

common difference of A.P=-2

then first four terms of A.P

T1 = -2

T2=-4

T3=-6

T4=-8

Step-by-step explanation:

T1 = a = -2

T2 = a+d = -2+(-2)= -4

T3 = a+2d = -2+2×(-2)= -2-4=-6

T4 = a+3d = -2 +3×(-2) = -2-6= -8
