Answer:
- -25, 4, 33, 62, 91, 120, ...
Step-by-step explanation:
<h3>Given</h3>
<u>The arithmetic sequence</u>
- .. , 4, ?, ?, ?, 120, ...
<h3>To find:</h3>
<h3>Solution</h3>
<u>Let the first term a₁ = x, and common difference = d then we have:</u>
- a₁ = x
- a₂ = x + d = 4
- ...
- a₆ = x + 5d = 120
<u>The difference of the 6th and 2nd terms:</u>
- a₆ - a₂ =
- a + 5d - x - d = 120 - 4
- 4d = 116
- d = 116/4
- d = 29
<u>Then we get the first term and other missing terms:</u>
-25, 4, 4+29 = 33, 33+29 = 62, 62 + 29= 91, 91+29 = 120, ...
Answer: 4.5
Step-by-step explanation:
S= ut + 1/2(at)
S= 10(1/2) + 1/2(-2x1/2)
S= 5 + 1/2(-1)
S= 5 + (-.5)
S= 4.5
Answer:
$11.25
Step-by-step explanation:
1.5×7.5=11.25
Example: -2 times -2= 4 -2times 2= -4
So basically when you divide and multiply the same signs . the answer is positive. if the signs are different then the answer is negative
