Answer: 117
Step-by-step explanation:
Formula for arithmetic sequence is:
= a + (n - 1)d
22nd term = a + (n - 1)d
= a + (22 - 1)d = a + 21d
where, a = 12
d = 17 - 12 = 5.
Therefore, 22nd term will be:
= a + 21d
= 12 + 21(5)
= 12 + 105
= 117
The 22nd term is 117
The answer for this question is 1468
Answer:
70
Step-by-step explanation:
Set up the problem like this: x - 4 + 8 = 44
x-4+8=44 (8-4)
x+4=44
-4 -4 (subtract 4 from both sides)
x=40
Answer: the number is 40.
