Anyone know this question ??

no but i can create a code from this:

Step-by-step explanation:

java:

int steps = 4;

for (int i = 0; i < steps; i++) { }

this part is psuedocode:

print(i) blocks

there will be 36 squared.

each new step adds one more than the last step added.

f(1) = 1

f(2) = 3 = 1+2

f(3) = 6 = 1+2+3

f(4) = 10 = 1+2+3+4

the pattern is now clear hopefully

f(8) = 1+2+3+4+5+6+7+8 = 1+8 + 2+7 + 3+6 + 4+5 = 9+9+9+9 = 9*4 = 36

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
