Answer:It's an arithmetic sequence with a common difference, d, = 4
A1 = 8
A2 = 8+4 = 12
A3 = 12+4 = 16 = 8+4(3-1) = 8+4(2) = 8+8
AN = A1 + d(N-1)
AN = 8 +4(N-1) = the Nth term in the sequence

Answer:
42.7 cm sq.
Step-by-step explanation:
small/large = 16 / 122
16/122 = S / 56
S = 56 * (16/122) = 7.34...
however not in the choice
ah ha..
You meant : 12.2 sq. cm : 16 sq. cm = small / large
so 12.2 / 16 = S / 56 cm
S = 42.7 sq. cm
The answer is 327. Remember that when you multiply a number by ten, you move the decimal point to the right one place.
Hope that helped you.
