Question

Help??????????????????(

Answer 1

-2, 1, 6 and the 10th is 97

Explanation:

to find the terms, in a row, replace n with 1

nth = 1^2 -3 -2 is the answer (1^2) is 1 -3 = -2

then replace the n with 2, 3, 4 etc till you have your sequence

nth = 2^2 -3 1 is the answer (2^2) is 4 -3 = 1

nth = 3^2 -3 6 is the answer (3^2) is 9-3 = 6

nth = 4^2 -3 13 is the answer (4^2) is 16-3 = 13

nth = 5^2 -3 22 is the answer (5^2) is 25-3 = 22

etc to 10

nth = 10^2 -3 97 is the answer (10^2) is 100 - 3 = 97

sequence is -2, 1, 6, 13, 22, . . . . 97

Answer 2

Explanation:

Tn = n² - 3

Now

the first three terms

t1 = 1² - 3 = 1 - 3= -2

t2 = 2² - 3= 4 - 3 = 1

t3 = 3² - 3 = 9 - 3 = 6

----------------

The first three terms are -2 , 1 , 6

and

tenth term

t10= 10² - 3= 100-3 = 97

Hope it will help you :))
