The sum of the first 10 terms of the sequence an = 4n - 3 can be found by plugging in n=1, n=2, n=3, ..., n=10 into the formula and then adding up the results.
Number of terms = 10
Sum = 10/2 * (2a + (n-1)d)
= 5 * (2(4*1 - 3) + (10-1) * 4)
= 5 * (2(4 - 3) + 9*4)
= 5 * (2(1) + 36
= 5 * (2 + 36)
= 5 * 38
= 190
Therefore, the sum of the first 10 terms of the sequence is 190.
So, the answer is 190.
