From the 8th to the 13th there are five numbers, and the difference between the 8th and the 13th is 20-12.5=7.5, so the difference between two neighboring number is 7.5÷5=1.5
from the 13th and the 25th there are 12 numbers, so the total difference is 12*1.5=18
so the 25th term is 20+18=38
30,343,154 should be it. Haven’t done that in a while
You can try this for any value of n, if you find one instance that is false, the statement is false.
Let's take n=5, then the following should be true:
F₇ is the sum of the first 5 terms.
F₇ = 13, and 1+1+2+3+5 = 12; they're different.
So the statement is false.
M = 25 - 31 / 3 - 4
m = - 16 / - 1
m = 16
25 = 16(3) + c
c = 25 - 48
c = - 23
y = 16x - 23
