Your answer to this is 200
2 cm. because you would subtract 5 and 3.
Step-by-step explanation:
As we can see that common difference is increasing to one more digit after every term
so it means
a21 = 231
y = 3x-2x∧2+5x∧3
When we replace x with value 3 we get
y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126
good luck!!!
