Question

Pls help! (don't give wrong answer pls)
Decide whether the sequence is Arithmetic, Geometric or Neither.
4, 9, 16, 25, ...

Answer 1

Check arithmetic

t4-t3 t3-t2

25-16 16-9

=9 =7

sequence is not arithmetic bcoz t4-t3 is unequal to t4-t3

check geometric

t4÷t3 t3÷t2

25÷16 16÷9

=1.6 1.7

sequence is not geometric bcoz t4÷t3 is unequal to t3÷t2

neither
