Question

Find the first three terms of the sequence below.

Answer 1

Answer:

T1=1-2-6= -7

T2=4-4-6= -6

T3=9-6-6= -3

Answer 2

to find the first term n=1

substitute n for 1 in the equation

T1=2(1)-6

T1=2-6=-4.

to find the 2nd term n= 2

T2=2(2)-6

T2=4-6=-2

to find the third term n=3

T3=2(3)-6

T3=6-6=0.

therefore,1st term=-4.

2nd term =-2.

3rd term =0.
