Question

write first four terms of the ap, when the first term a and the common d are given as follows- a=4,d=-3​

Answer 1

Answer:

4,1,-2,-5

Step-by-step explanation:

Using the formula an = a + (n-1) d

a1 = 4+(1-1) -3

= 4

a2 = 4+(2-1)-3

= 4-3

= 1

a3 = 4+(3-1)(-3)

= 4-6

= -2

a4 = 4+(4-1)(-3)

= 4-9

= -5

Therefore, the first four terms of the AP are 4,1,-2,-5,......
