Question

Write first three terms of AP whose first term is -2 and common difference is 2

Answer 1

Answer:

a= -2 and d=2

Step-by-step explanation:

so a1 = -2

a2=a+d = -2+2 = 0

and a3 = a +2d = -2 + 4 = 2

Answer 2

Step-by-step explanation:

GIVEN : First term a = -2

Common difference d = 2

a(n) = a + (n-1)d

= -2 + (1-1) 2

=-2 + 0

= -2

1st term is -2

For second and third terms respectively , substitute 2 and 3 in n to get the AP
