Determine the 20th term of the sequence:-14,-8, -2, 4, 10, ...

100

Step-by-step explanation:

add 6 20 times (-14,-8,-2,4,10,16,22,28,34,40,46,52,58,64,70,76,82,88,94,100)

100.

Explanation:

Here the sequence is;

-14,-8,-2,4,10

Since the common difference is 6, its n term must be generated by 6n. But the first term is -14. so, the nth term must be 6n-20.

Because,

t1 = 6×1-20 = -14

t2 =6x2-20= -8

t3 = 6×3-20= -2

Similarly

nth term = 6n-20.

so,

t20 = 6×20 -20= 120 -20 =100.

Hope it will be helpful.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
