Question

find the first term and the common difference of the AP 5,-1,-3,-7..... *

1 point

a = 5, d = -4

a = 6, D = -5

a = -5, d = -4

a = -6 d = 4

​

Answer 1

Answer:

Solution :

Given A.P is 5 , 1 , -3 , -7 , ....,

first term = a = a1 = 5 ,

second term = a2 = 1 ,

Common difference ( d ) = a2 - a1 = a3-a2

d = 1 - 5

d = -4

Therefore ,

first term = a = 5 ,

common difference = d = -4

Step-by-step explanation:

Answer 2

Answer:

a=5 d=-6

Step-by-step explanation:

1. the first term is 5 a=5
2. the common difference in A.p is d=t2- t1
3. d=-1 - 5
4. d=-6
5. a=5 ,d=-6
