Answer 1

Answer:

Given

first term = 4

common difference= -3

to find

a4

Solution

a4= a+3d

put the given value

a4= 4 + 3 x (-3)

a4= 4 -9

a4= -5

Answer 2

Step-by-step explanation:

a = 4 & d = -3

a = 4

a2 = a + d = 4 + (-3)

= 4-3 = 1

a3 = a2 + d = 1 + (-3)

= 1 - 3 = -2

a4 = a3 + d = -2 + (-3)

= -2 - 3 = -5

OR

a4 = a + (n-1) d

= 4 + (4-1)(-3)

= 4 + 3(-3)

= 4-9

= -5

you can do by both ways
