Step-by-step explanation:
Product of number y and 7 is 7y
One less is 7y-1
-50 + 17 = - 33
-33 + 17 = -16
- 16 +17 =1
This is arithmetic sequence, where 1st term is -50,
and common difference is 17.
Formula for the term of arithmetic sequence
a(n) = a(1) +d(n-1) = -50 +17(n-1) = -50 +17n - 17 = -67 +17n
So, we can write a formula
a(n) = -67 +17n
Answer:
£16.25
Step-by-step explanation:
Jon. £9 to nearest pound so £9.50
Ellie. £6.50 to the nearest 50p so £6.75. £
9.5+6.75 = £16.25
¹/₄y + 9 = ½
¹/₄y = ½-9
¹/₄y = -¹⁷/₂
y = -34
