maths

types of seqences

liner/anthmetic: that go up or down in the same gaps

Geometric:multipled/divided by a constand number to get next get to the next term,for example, 1,3,9,27,81 (x3 each gap)

fibonaci-style: is where the previous two terms are added together to get the next terms e.g 1,1,2,3,5,8,13

quadractic: have second gap size the same  e.g "1,4,9,16,25,36" first gap are 3,5,7,9,11 then second are all 2 like this:

angles 

acute: is less than 90

right angle: exactly 90

obtuse: is bigger than 90

reflex: between 180…
