If you go do ur assignments
Answer:
an = 9n -16
Step-by-step explanation:
First find the common difference, d
Take the second term and subtract the first
2 - (-7) = 2+7 = 9
We are adding 9 each time
Check 2+9 =11, check 11+9 = 20 check
The first term in the sequence is a1 so a1 =-7
an = a1 + d(n-1)
an = -7 + 9(n-1)
Distribute
an = -7 +9n-9
Combine like terms
an = 9n -16

Step-by-step explanation:
Let 7.1239 is a decimal number. Now, we have to round the given decimal number to its nearest thousandth.
Step 1: Identity the thousandth digit. (Here, 3 is the digit which is in thousandth place)
Step 2: Now, look at the digit, which is next to the thousandth place. If that digit is less than 5, round down the thousandth digit. If that digit is greater than or equal to 5, round up the thousandth digit. From the example given above, the digit next to the thousandth digit (i.e., 9) is greater than 5, so we have to round up the thousandth digit.
Step 3: Thus, the number 7.1239 rounded to the nearest thousandth is 7.124.
The answer is 6.33 units.
