Question

Write theFirst four termsOf AP when a= 4 d=-3

Answer 1

Answer:

4, 1, -2, -5

Step-by-step explanation:

Here, a = 4

d = -3

We know that, an = a + (n-1)d

a1 = 4 + (1-1)-3

a1 = 4 + 0

a1 = 4

Similarly, a2 = 4+(2-1)-3

a2 = 4-3

a2 = 1

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

a3 = 4+(2)-3

a3 = 4-6

a3 = -2

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

a4 = 4+(3)-3

a4 = 4-9

a4 = -5

Therefore, the AP becomes: 4, 1, -2, -5
