Question

find the first 4 terms of AP whose first term is -2 and common difference is -2.

Answer 1

A=-2
D=-2
SO, A1=-2, A2=-4, A3=-6 AND A4=-8





THESE ANSWER WAS TOO EASY

Answer 2

a = - 2

d = - 2

We know that a is the first term...

So, T1 = a = - 2

Now,

Tn = a + (n-1) d

Term 2 = a + (2-1)d

T2 = a + d

= - 2 - 2

= - 4

Similarly,

T3 = a + 2d

= - 2 + 2(-2)

= - 2 - 4

= - 6

And.

T4 = a+ 3d

= - 2 + 3(-2)

= - 2 - 6

= - 8
