Answer:
The first 5 terms of the sequence are 2, 4, 8, 16 and 32.
Step-by-step explanation:
Given:
= 2
= 2
-----------------(i)
To get the first 5 terms of the sequence, substitute in turn, n = 1, 2, 3, 4, 5 into equation (i).
The first term (when n = 1) has been given as:
= 2
The second term (when n = 2) is given as:
= 2
= 2 (but = 2 )
=> = 2(2)
=> = 4
The third term (when n = 3) is given as:
= 2
= 2 (but = 4 )
=> = 2(4)
=> = 8
The fourth term (when n = 4) is given as:
= 2
= 2 (but = 8 )
=> = 2(8)
=> = 16
The fifth term (when n = 5) is given as:
= 2
= 2 (but = 16 )
=> = 2(16)
=> = 32
Therefore, the first 5 terms of the sequence are 2, 4, 8, 16 and 32.
Answer:171 and 172
Step-by-step explanation;
171+172=343
Answer:
101
Step-by-step explanation:
<span>The next number should be 4. If you look at every other number, even and odd alternate. 2 is even, 7 is odd, etc. Since 9 is odd, the next number should be even. To figure out what number specifically, you will want to break up the numbers into three columns. 2 3 __
7 12 17
8 9 10 From here, you can see that the pattern will be adding 1 for the top row, 5 for the middle row, and 1 for the bottom row. Since the unknown number is on the top right of the first row, you will add 1 to 3, and the answer is 4.</span>
