Answer: The Given sequence is 9, 10, 11, 12
We need to find the expression to describe the sequence.
Let be the term of the sequence.
Let n represent the position of the term.
Let a be the first term in the sequence.
and d be the common difference between the sequence
Hence the expression to find the above sequence is given below;
when n=1 d= 1 a = 9
when n=2 d= 1 a = 9
when n=3 d= 1 a = 9
when n=3 d= 1 a = 9
Hence the expression is

Answer: 39. x= 37, 41. x=7, 43. x = 29
Step-by-step explanation:
39. 2x + 4 + 2x - 9 + x = 180
5x - 5 = 180
5x=185
185/5
x=37
41. 90 + 8x - 1 + 4x+7 =180
8x-1+4x+7=90
12x+6=90
12x=84
84/12
x=7
36+x=2x+7
36=x+7
29=x
Hope this helps.
