Question

write first four terms of a.p where a= -1.25, d= -0.75
​

Answer 1

Answer:

Four terms of a. p = -1.25, -2, -2.75, -3.5

Answer 2

Answer:

a = -1.25

d = -0.25

therefore a1 = -1.25

a2 = a1 + d = -1.25 + (-0.75) = -2

a3 = a2 + d = -2 + (-0.75) = -1.25

a4 = a3 + d = -1.25 + (-0.75) = -2

Thus the A.P. will be:

-1.25, -2, -1.25, -2,.....
