Question

The algebraic form of an arithmetic sequence id 5n+4.

a) What is its first term?

b) what is the difference of its 10 th and 20 th terms?

c) Can the difference of any two terns of this sequence be 368? Justify
​

Answer 1

Step-by-step explanation:

a) put n = 0

first term is 5*(0) +4 = 4

b) 10th term = 54

20th term = 104

difference = 50

there could be a direct formula for it,I don't remember though.

c)No,

the difference can only be a multiple of 5
