Question

Write the first four terms in the multiplication pattern given by the formula:

10 · 5n

Answer 1

we have that
an=10 * 5n---------------> an=50*n

then

for n=1
a1=50*1=50

for n=2
a2=50*2=100

for n=3
a3=50*3=150

for n=4
a4=50*4=200


the answer is
the first four terms are [50,100,150,200]
