Question

consider the arithmetic sequence is 6,10,14
(a) what is it's common difference
(b) what is it's 10th term?
(c) what is it's algebraic from? ​

Answer 1

a. common difference is 4

b.10th term is 54.

Answer 2

Answer:

a) common difference= a2-a1

10-6=4

b)an= a+(n-1)*d

a10= 6+(10-1)*4

a10=6+(9)*4

a10=6+36

a10= 42

c)an= a+(n-1)*d

Sn= n/2(a+an)
