Answer:

100.

Step-by-step 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.
