An = -2n + 4 ; where n is the sequence number or order.
a1 = -2(1) + 4
a1 = -2 + 4
a1 = 2
a2 = -2(2) + 4
a2 = -4 + 4
a2 = 0
a3 = -2(3) + 4
a3 = -6 + 4
a3 = -2
a4 = -2(4) + 4
a4 = -8 + 4
a4 = -4
So the first four terms of the sequence are: 2, 0, -2, -4
Hello,
Answer B
Let's n an integer
n=100*[n/100]+r
As 100 is divisible by 4 , for n divisible by 4 r must be divisible by 4.
Pay attention to the order of ur letters...
ABC = GXK....this is saying that : < A = < G.....and < B = < X....and < C = < K
so these are ur congruent angles
ABC = GYX...this is saying : side AB = side GY and side BC = side YX and side AC = side GX
and these are ur congruent sides
