The rule of given table is (a÷2)-(b÷3).
Step-by-step explanation:
From the given table it is clear that
8 becomes 3
24 becomes 9
40 becomes 15
Rule
(8÷2)-(3÷3) = (4-1) = 3
(24÷2)-(9÷3) = (12-3) = 9
(40÷2)-(15÷3) = (20-5) = 15
So, the equation will be
(a÷2)-(b÷3)
Answer:
Step-by-step explanation:
hello :
a(n) -a(n-1) = -16 (common differnce for arithmetic sequence)
-44-(-28) = (-28)-(-12) = -16
the ni-eme term is : a(n) = a(1) +(n-1)d d = -16 and a(1) = -12
so : a(n) = -12 +(n-1)(-16)
a(n) = -16n+4
continue for 61st term n = ?????
when : n= ? a(?) = -16(?)+3 =.....
The first two are equivalent to 15 = k + 13
8 = k + 13 - 7 → ( add 7 to both sides )
8 + 7 = k + 13 ⇒ 15 = k + 13 ' is equivalent '
12 = k + 13 - 3 → ( add 3 to both sides )
12 + 3 = k + 13 ' is equivalent '
