The arithmetic sequence is 6, 12, 18, 24,......
\The first term .
Find the common difference by subtracting successive terms.
\The common difference (d) is 6.
Find the nth term, so using the nth term formula: .
(Substitute
, and d = 6)
Distibute terms using distributive property: a(b – c)= ab – ac.
\Apply commutative property of addition: a + b = b + a.
\ (Apply additive inverse property:
)
Find the 10th term in the sequence.
\ (Substitute n = 10)
(Multiply:
)
