Question

write the first two terms of the AP when the first term is -1 and common difference is 1 by 2​

Answer 1

Answer:

first term = -1, second term = -1/2

Step-by-step explanation:

second term = f + d

=-1+1/2= -2+1/2=-1/2

Answer 2

$\huge\sf\pink{Answer}$

☞ Your Answer is -1 , -0.5

$\huge\sf\blue{Given}$

✭ First Term = -1

✭ $\sf Common \:Difference\: = \: \dfrac{1}{2}$

➢ First two terms of the AP?

$\huge\sf\purple{Steps}$

❍ To get the terms of A.P, follow the standard form of A.P, i.e., (a + d), (a + 2d) and (a + 3d).

$\sf\orange{a_1 = -1}$

$\sf\red{a_2 = -1 + 0.5 = -0.5}$

Hence, the first two terms are - 1 and - 0.5.

$\sf{\underline{\bullet{\; Arithmetic \:Progression}}}$

A list of numbers in which every term is obtained by adding of subtracting a fixed number to the next term except the first term, is called Arithmetic Progression (AP).

The general form of A.P is -

a, (a + d), (a + 2d), (a + 3d)..... (a +nd)
