A^2 + b^2 = c^2
297^2 + 394^2 = C^2
88209+155236=243445
take the square root of 243445
you get 493.4
which in your answer they're rounded
so your answer is
C. 493
There may be more than one solution, but if we take the difference between the numbers of the sequence, we get
3-1, 11-3, 43-11
=2,8,32
which are powers of 2
=2^1, 2^3,2^5
If we believe the next difference is 2^7=128, then the next in the sequence will be 43+128=171
D.) 15s
The fourth term refers to the 15s together, not any part of the term apart.
Can you explain the question in words please?
