Without using table or calculator evaluate log 25 base 5
2
The nth term is: 5-6n
13 + 6 = 19 19 + 6 = 25. 19 X 6 = 114.
13+2=15+4=19+6=25 The 2 keeps doubling. Hope this helped you!!
19
From the first term subtract 19 to get the second, and continue to subtract the next smaller odd number to proceed down the line:100 (-19) 81 (-17) 64 (-15) 49 (-13) 36 (-11) 25 (-9) 16
what will the eight number be. 1, 7, 13, 19, 25, 31 ...
[ 25 - 6n ] is.
6n - 5
The nth term is: 5-6n
T(n) = 25 - 6n
13 + 6 = 19 19 + 6 = 25. 19 X 6 = 114.
It is: 6+80-19 = 67
13+2=15+4=19+6=25 The 2 keeps doubling. Hope this helped you!!
The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 13
19/25 = 0.76 13/40 = 0.325 0.76 - 0.325 = 0.435 ----------------------------------------------------------------- Working in fractions: To add/subtract fractions they need to have the same denominator: 19/25 - 13/40 = (19×8)/(25×8) - (13×5)/(40×5) = 152/200 - 65/200 = (152-65)/200 = 87/200
Sum is 25, difference is 13 So twice the bigger is 25+13 = 38 ie bigger is 19 and twice the samller is 25-13 = 12 ie smaller is 6 So their product = 19*6 = 114
Assuming the pattern would continue: 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13...
