Question

if a = 10 and = 10 find four terms of AP​

Answer 1

Step-by-step explanation:

a = 10

d = 10

a2 = a + d

=10 +10

= 20

a3 = a + 2d

= 10 + 2 (10)

= 10 + 20

= 30

a4 = a + 3d

= 10 + 3 (10)

= 10 + 30

= 40

Therefore ; A.P. is 10, 20, 30, 40

Answer 2

Answer:

given:a=10

d=10

soln:four terms of ap are a;a+d;a+2d;a+3d

a=10

a+d=10+10=20

a+2d=10+2×10=30

a+3d=10+3×10=40
