Question

write the first 4 terms of the AP whose first term is -2 and the common difference is -2.​

Answer 1

Step-by-step explanation:

common difference(d)=-2

firsr term (a)=-2

using formula

$an = a + (n - 1)d$

$a2 = - 2 + (2 - 1) - 2$

$a2 = - 3$

now the 3rd term

$a3 = - 2 + (3 - 1) - 2$

$a3 = - 2$

now the 4th term

$a4 = - 2 + (4 - 1) - 2$

$a4 = - 1$

the four terms are

-2,-3,-2,-1
