A lot of possibilities. A few ones: * (9-8) * (7-6) * (5-4) = 1 * 9 + 6 + 5 - 8 - 7 - 4 = 1 * 7*4 / (9+8+6+5) = 1 * 6*5 - 7*4 - 9 + 8 = 1 * etc., etc.
There are many. Her is one: 1 + 4 - 5 - 7 + 9 + 11 = 13
two numbers multiplied together that gives you 20 are 10 and 2. also have 5*4, 1*20, 2.5*8 ect
big/small so if it was 1/4 2/8 divide to numbers across 8/4 and 2/1 i THINK
1 and 56, 2 and 28, 4 and 14, and 7 and 8.
-1
There are 4 such integers: 25, 49, 73, 97
Rectangular numbers are of the form n(n+1) for n = 1, 2, 3, 4, 5, 6, ... The first few rectangular numbers are: 2, 6, 12, 20, 30, 42, ...
There is no formula, but I can point out that: between the numbers you get: +1,+2,+3,+4+5... so the next term would be +6 or 21
1 x 28, 2 x 14, 4 x 7
Pb(C2H302)4 **** Numbers are subscripts
The next two can be anything you want them to be (as a formula can be found which matches the sequence so far and gives you any two numbers you want). However, the simplest formula is probably "the next term is the current term multiplied by 1.5" giving the next two as 20.25 and 30.375 The formula for the nth term is given by t(n) = 4×1.5^(n-1) for n = 1, 2, 3, ...
When writing a range of numbers, square brackets are used to indicate the end number is included and round brackets are used to indicate the end number is excluded.examples:[1, 4] = all numbers ≥ 1 and ≤ 4(1, 4] = all numbers > 1 and ≤ 4[1, 4) = all numbers ≥ 1 and < 4(1, 4) = all numbers > 1 and < 4
