SOLUTION:
Step 1:
In this question, we are meant to find the patterns to check:
25x10 = 250.

It is multiplication. Multiplication is another name for repeated addition.
Step 2:
Therefore, we add 10 +10 + 10 + 10 +10 +10 + 10 +10 +10 + 10 +10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 +10 + 10 + 10 = 250




Step 3:
Here n is the variable, n = 1 to 25.
Therefore, the pattern is n x 10 where n = 1 to 25.
