Question

How do I find the next number in the patter, 5,11,29,83,245 ?

I think it's 454, but not sure how to figure it

Answer 1

look at the differences between each number and the next
6 18 54 162
each difference is 3 times the one before it
so the next difference is 3 * 162
which is 486
so the next number is 245 + 486 = 731 I believe

Answer 2

i think the next number is 731 too. However my way of doing it is by multipling 3 to the number and substract by 4. So 245*3 is 735 and 735-4 is 731.

Answer 3

What is the next term of 245
