Answer:
49
Step-by-step explanation:
Let x be unknown number which should be added to numbers 1, 11, 23 to get geometric progression. Then numbers 1 + x, 11 + x, 23 + x are first three terms of geometric progression.
Hence,
and
Express q:
Solve this equation. Cross multiply:
y=-8x+5
The others have a slope of -2, 7, and 6, which is not as steep as -8.
16.65
37 * 0.45 = 16.65
positive 33
a negative times a negative is a positive and 3 times 11 is 33
