Answer:
163
Step-by-step explanation:
180 is the sum of all degrees.
subtract 22 from that to get 158
so X-5 = 158
you add a 5 to both sides: X+5-5=158+5
you cancel the fives in the first side of the equation and add 5 to 158 on the other side.
X=158+5
X=163

Answer:
4, 7, 12, 19 and 103
Step-by-step explanation:
Substitute n = 1, 2, 3, 4, 10 into the n th term formula, that is
1² + 3 = 1 + 3 = 4
2² + 3 = 4 + 3 = 7
3² + 3 = 9 + 3 = 12
4² + 3 = 16 + 3 = 19
Thus the first 4 terms are 4, 7, 12, 19
10² + 3 = 100 + 3 = 103
Thus the 10 th term is 103
