1.5.10,16 _ _ what comes subsequent and also 1,2,4,7,11 _ _?
Question:
Answers:
in the first on in that is an addition of 4 after 5 then 6 etc (+1 respectively time. Therefore the nxt 2 numbers will be 23 (+7) and 31 (+8)
in the second one at hand is an addition of 1 consequently 2 then 3 next 4 (+1 each time). Therefore the nxt two numbers are 16 (+5) and 22 (+6)
23
&
16
Each time you affix 1 more than last time to previous no.
first set of numbers
+4 next +5, +6, +7
Second set
+1+2+3+4+5.
first 3 number equal total so 5 10 16 will equal 31
and is it prime numbers so 13
you have to find the guide: for the first one, the pattern is that you add on one more respectively time. 1+4=5, 5+5=10, 10+6=16, so : 16+7=23 and 23+8=31, so the next two numbers within the pattern are 23 and 31
the subsequent one has equal pattern; see if you can numeral it out!
If this is homework then use the answers already given.
But if this is something newly for fun then why not be obtuse and grant these answers -
First one - 22 and 29 (Davenport-Schinzel numbers)
Second one - 13 and 14 (values of n for which 16n+15 is prime)
Sorry, I couldn't resist. :o)
