Question

0-2 write the comed number in the boxes from the
following A.P
-3 -8 -13 -18​

Answer 1

$\huge\mathbb\pink{Answer}$

Here a = -3

d = a + (-8)

d = (-3) -(8)

d = -5

____________

So the difference between two numbers is -5.

➭Let us complete AP further.

-3, -8 , -13 , -18 , -23, -28 , -33 , -38

Just add -5 to every number.

Answer 2

Question:-

Write the next number in the boxes from the following A.P -3 -8 -13 -18.

$\huge{\dag\:{\underline{\boxed{\mathfrak{\purple{Answer}}}}}}$

➴ Numbers are -3, -8, -13, -18

➴ To find next numbers

_________________

a = -3

d = -5

➦ a1 = a = -3

➦ a2 = a1 + d =

-3 + (-5) = -8

➦ a3 = a2 + d

-8 + ( -5) = -13

➦a4 = a3 + d

-13 + (-5) = -18

--------------°°°

Similarly it will goes on and we will get

➭ -3, -8, -13, -18, -23, -28

➴What is Arithmetic Progression (A.P)

➺Successive terms are obtained by adding a fixed number of preceding term. This is called Arithmetic Progressions.

➴ Here a is the first term.

➴ Here d is the common difference.
