Question

For an AP, a = 3 and d = 0.25, then the AP is??​

Answer 1

Step-by-step explanation:

Solution

a = first term

d = difference

n = nth term

(1) a=10;d=10

⇒10;a+d;a+2d;a+3d

⇒10;10+10;10+20;10+30

⇒10;20;30;40

(2) a=−2;d=0

⇒a;a+d;a+2d;a+3d

⇒−2,−2+0;−2+0;−2+0

⇒−2,−2,−2,−2

(3) a=4,d=−3

⇒a,a+d;a+2d;a+3d

⇒4,4−3;4−6;4−9

⇒4,+1;−2,−5

(4) a=−1;d=

⇒a;a+d;a+2d;a+3d

⇒−1;−1+

(5) a=−1.25;d=−0.25

⇒a;a+d;a+2d;a+3d

⇒−1.25;−1.25−0.25;−1.25−0.5;−1.25−0.75

⇒−1.25;−1.5;−1.75;2
