Answer: n = 130
Step-by-step explanation:
The sequence is an Arithmetic progression ( AP )
The last term of the sequence is (L) is 394 with the formula
L = a + ( n- 1 )d . From the sequence, a = 7, d ( common difference ) = 3 and L ( last term ) = 394, and n = ?
Put those values in the formula above and solve for n.
a + ( n - 1 )d = L
7 + ( n - 1 ) x 3 = 394
7 + 3n - 3 = 394
4 + 3n = 394
3n = 394 - 4
3n = 390
n = 130
I would say 1700 , I hope this helps
Slop interest form is the amswer
Area of circle = pie x r^2
GIVEN: radius=22cm REQUIRED: Area = ?
SOLUTION: pie x 22^2 = 484piecm^2
Answer is OPTION D
<span>The solution would
be like this for this specific problem:
</span>
(2x+5)/7 = 1/x
(2x+5) x = 7
2x² + 5x - 7 = 0
( x -1) ( 2x + 7) = 0
x = 1 ( Omit x = -7/2)
