What is the sum of the sequence 152,138,124, ... if there are 24 terms?

N76 [4]

Answer: -216

Step-by-step explanation:

To solve the exercise you must use the formula shown below:

$Sn=\frac{(a_1+a_n)n}{2}$

Where:

$a_1=152\\a_n=a_{24}$

You should find $a_{24}$

The formula to find it is:

$a_n=a_1+(n-1)d$

Where d is the difference between two consecutive terms.

$d=138-152=-14$

Then:

$a_{24}=152+(24-1)(14)=-170$

Substitute it into the first formula. Therefore, you obtain:

$S_{24}=\frac{(152-170)(24)}{2}=-216$

What 1 7/8 × 2 3/8 will be equal to,greater than or less than 2 3/8

Sunny_sXe [5.5K]

Answer:

greater than

Step-by-step explanation:

Since 2 $\frac{3}{8}$ is being multiplied by a number greater than 1, the result will be greater than 2 $\frac{3}{8}$

If the multiplier was 1 then the result would be equal to 2 $\frac{3}{8}$

If the multiplier was between 0 and 1 the result would be less than 2 $\frac{3}{8}$
