n = 1, 2, 3, 4, 5 a1 = 3, a2 = 7, a3 = 11, a4 = 15, a5 = 19, ..., an = 4n -1
an=an-1 To use this formula, you start of with a value on the first term, but theoretical, it'd turn out like this: a1=a1-1=a0 a2=a2-1=a1 a3=a3-1=a2 a4=a4-1=a3 a5=a5-1=a4 Where a0 would be your starting term (this formula is based on the previous term, and that's why you must have a value to start off with).

Given: a1=1024 a4=-16 Find: a7 Formula: an=a1rn-1 To get the ratio, r: a4=a1r4-1 -16=1024r4-1 -16=1024r3 -16/1024=1024/1024r3 -1/64=r3 -1/4=r Substiture r=1/4 to the formula to get a7 a7=a1r7-1 =a1r6 =1024(-1/4)6 =1024(1/4096) =1/4 =0.25 Therefore the 7th term=0.25 FromC2H5.OH: The fourth term is the geometric mean of the first and seventh terms and is therefore the square root of their product; this means that -16 squared = 1024 x a7 ie a7 = 256/1024 = 0.25
A linear series with "i" terms can be summed by finding the average of the first and last terms, then multiplying by the amount of terms.This sequence can be written as follows:ai= 11 + 1(i-1)= 11 + i - 1= 10 + i11 is the first term, 1 is the difference between terms which gets multiplied by (i-1)So the fourth term a4= 10 + 4 = 14Sum total = i * (a1+ ai)/2 (no. of terms * average of first and last term)= 10 * (11 + 20)/2= 10 * (31/2)= 155

An A4 paper is just below 30cm high(i think its 29 something)
