28 - 8n
If that's 12, 48 and 16, the LCM is 48. If that's 124 and 816, the LCM is 25296.
It appears that the nth term is (8 + 2n).- For n=12, (8 + 2n) = (8 + 24) = 32 .- For n=77, (8 + 2n) = (8 + 154) = 162.
Prove it by induction on n, use 0 or 1 as base cases.
The exponential expression a^n is read a to the nth power. In this expression, a is the base and n is the exponent. The number represented by a^n is called the nth power of a.When n is a positive integer, you can interpret a^n as a^n = a x a x ... x a (n factors).
