Find the next three terms in each sequence. Then write an equation for the nth term of the
1 answer:
Step-by-step explanation:
a) clearly, the sequence is created by subtracting 12 from one term to the next.
so, d = -12
a (= a1) = -5 (the first term is the start value)
the next 3 terms are then
-41, -53, -65
a28 = -5 + 27×-12 = -329
b) the sequence is created by adding 6 from term to term.
so, d = 6
a (= a1) = 8
the next 3 terms are
26, 32, 38
a77 = 8 + 76×6 = 464
