Question

Write the first term and common differences of arithmetic sequence whose algebraic expression is 3n+5

Answer 1

Step-by-step explanation:

a)The distance between two stations is 420 km. A train takes 4 hours to cover this distance. Calculate

the speed of the train.

b)How does the process

Answer 2

Answer:

first term of AP is 8

common difference is 3

Step-by-step explanation:

an= 3n+ 5 ( given)

first term of AP

a1= 3(1) +5

a1= 3+ 5

a1= 8

second term of AP

a2= 3(2) +5

a2= 6+5

a2= 11

common difference d

d= a2-a1

d= 11-8

d= 3
