 Question 604718: Find the number of terms in the sequence 5,2,-1,...,-37 The next term in 3,6,12,24,48,... The 100th term in 6,8,17,26,35,... Given that the sequence 1,6,x,y,20,...is a Fibonacci sequence, find x and y.Answer by stanbon(57347)   (Show Source): You can put this solution on YOUR website!Find the number of terms in the sequence 5,2,-1,...,-37 The next term in 3,6,12,24,48,... --- Note: It looks to me like the next term is -4 ================================================ The 100th term in 6,8,17,26,35,... a(100) = a(1)+(n-1)d = 3 + 99*(-3) = -294 =========================== Given that the sequence 1,6,x,y,20,...is a Fibonacci sequence, find x and y. x = 1+6 = 7 y = 6+7 = 13 =================== Cheers, Stan H.
